This is part of replacing can_gc with the new &JSContext/&mut JSContext

We modify CheckValidity and ReportValidity in various HTML Elements to
use the context instead of CanGc.
Testing: Compilation is the test as this is mostly mechanical.

Continuation of https://github.com/servo/servo/pull/42135, switch
Error::Type and Error::Range to also use CStrings internally, as they
are converted to CString for throwing JS exceptions (other get thrown as
DomException object, which uses rust string internally).
Changes in script crate are mechanical.
Testing: Should be covered by WPT tests.

This was the last failure in this directory. To fix it, I had to spelunk
into a couple of places:
1. We shouldn't use the `base_element()` of the document, but select the
first base element, regardless if it has an empty href or not
2. We didn't implement target checking for elements. Only some values
are valid and an empty target (which the test also confusingly uses) is
not valid. Hence, it should fallback to the base element
3. We weren't sanitizing the value in case it contains an ASCII tab or
newline + U+003C. This is true for both the form target as well as for
other link elements.
All in all, added a lot more specification text to figure out what was
going on.

Reviewable per commits:
As noted in
https://github.com/servo/servo/pull/42180#discussion_r2749861902
transmuting `&Reflector<AssociatedMemory>` to `&Reflector<()>` will
ignore AssociatedMemory information and thus it will not remove extra
associated memory. By returning `&Reflector<Self::ReflectorType>` from
`DomObject::reflector()` we will preserve this information and thus
correctly handle cases with associated memory. We also do not need
`overrideMemoryUsage` in bindings.conf anymore. 🎉
Instead of removing associated memory in drop code we should do it as
part of finalizers, otherwise we have problems in nested (inherited)
structs, where drop is run for both parent and child, but we only added
associated memory for child (on init_reflector) which already included
size of parent. The only exception here is promise, because it is RCed
and not finalized.
Testing: Tested locally that it fixes speedometer.

These changes introduce a new OriginSnapshot type, which is an immutable

modifier). This is now propagated as part of LoadData's origin, allowing
us to perform the same-origin-domain check for javascript: URLs as
needed.

This change brings Servo closer to the specification by removing the
unspecified sanitization flags used during parsing of input elements.
Instead we implement the lines of the specification that say to reset
resettable elements after parsing them. This forces a re-sanitization of
the default value (from the `value` attribute), clearing up the
confusion in parser comments.
In addition, specification text is added in the element creation code.
Testing: This just brings our code closer to the specification, so it is
covered by existing tests.

This change makes it so that all form controls are implemented with
shadow DOM, completely removing the legacy text content and selection
code paths for form controls. The motivation for this change is:
- to allow properly hit testing against the text nodes of `<textarea>`
and other widgets. This is important for implementing mouse-based
selection on the page.
- to simplify the way that form controls are implemented in general and
to prepare the way for proper implementations of the user interface of
other controls.
Testing: This should not change observable behavior at the moment,so
should be covered by existing WPT tests.

For some specific cases (one of them see below) where are requirement to
identify the reason of the attribute mutation (by whom/why it was
changed - by cloning, parser or directly), so the following `reason`
parameter was added to `AttributeMutation::Set` option.
Note that for the HTMLMediaElement the internal `muted` state should be
set to true when the element is created and the element has a `muted`
content attribute specified (should be done once on the first attribute
mutation caused by parser or cloning).

Servo has a lot of comments like this:
```rust
// https://example-spec.com/#do-the-thing
fn do_the_thing() {}
```
and I keep turning these into doc comments whenever I'm working close to
one of them. Doing so allows me to hover over a function call in an IDE
and open its specification without having to jump to the function
definition first. This change fixes all of these comments at once.
This was done using `find components -name '*.rs' -exec perl -i -0777
-pe 's|^([ \t]*)// (https?://.*)\n\1(fn )|\1/// <$2>\n\1$3|mg' {} +`.
Note that these comments should be doc comments even within trait `impl`
blocks, because rustdoc will use them as fallback documentation when the
method definition on the trait does not have documentation.
Testing: Comments only, no testing required

This replaces the implementation of is_empty and len with more efficient
representation without conversion
and allocation based on the underlying bytes.
For this we use a new view, EncodedBytesView.
Additionally, we implement a new macro `match_domstring_ascii!` which
allows simple match clauses
matching ascii strings with DOMStrings without conversion/allocation.
The macro will panic in debug builds if the strings are non-ascii but
will not match all DOMStrings correctly.
We replaced the usage of `DOMString::str()` in many places with this
macro.
Testing: len and is_empty were already covered by tests.
match_domstring_ascii! has more unit tests added with this PR.

This wrapper was added in order to eliminate the number of file
descriptors used accessing `/dev/urandom`, but these days `osrandom` and
by proxy `rand` will try to use `getrandom` on Linux and similar system
APIs on other platforms [^1].
This is a trial balloon for removing the wrapper, since almost all
modern Linux systems have `getrandom` (available since Linux
3.17).

This implements LazyDOMString (from now on DOMString) as outlined in
https://github.com/servo/servo/issues/39479.
Constructing from a *mut JSString we keep the in a
RootedTraceableBox<Heap<*mut JSString>> and transform
the string into a rust string if necessary via the `make_rust_string`
method.
Methods used in script are implemented on this string. Currently we
transform the string at all times.
But in the future more efficient implementations are possible.
We implement the safety critical sections in a separate module
DOMStringInner which allows simple constructors, `make_rust_string` and
the `bytes` method.
This method returns the new type `EncodedBytes` which contains the
reference to the underlying string in either format.
Testing: WPT tests still seem to work, so this should test this
functionality.

This change makes it so that `<iframe>` sanboxing is equivalent to the
one used for Content Security Policy, which is how the specification is
written. In addition, these sandboxing flags are passed through to
`<iframe>` `Document`s via `LoadData` and stored as
`Document::creation_sandboxing_flag_set`. The flags are used to
calculate the final `Document::active_sandboxing_flag_set` when loading
a `Document`.
This change makes it so that `<iframe>`s actually behave in a sandboxed
way, the same way that `Document`s with CSP configurations do. For
instance, now scripts and popups are blocked by default in `<iframe>`s
with the
`sandbox` attribute.
Testing: This causes many WPT tests to start to pass or to move from
ERROR to TIMEOUT or failing later. Some tests start to fail:
-
`/html/semantics/embedded-content/the-canvas-element/canvas-descendants-focusability-005.html`:
This test uses a combination of `<iframe allow>` and Canvas fallback
content, which we do not support.
-
`/html/semantics/embedded-content/the-iframe-element/iframe_sandbox_navigate_other_frame_popup.sub.html`:
This test is now failing because the iframe is sanboxed but in the
ScriptThread now due to `allow-same-origin`. More implementation is
needed to add support for the "one permitted sandbox navigator concept."

Previously, when we click any element, it would trigger "scroll into
view". What's worse, for an anchor `<a>`, clicking it would "scroll into
view" instead of navigating to the url until you retry the click. The
reason is that we built `scrollIntoView` into the focus transaction
system with default option. However, the default `preventScroll` for
`FocusOption` is false according to spec, which triggers "scroll into
view" by default with focus triggered by interaction.
This PR
1. Adds spec document for those which really expects "scroll into view",
i.e. `<form>` when validating data.
2. Make sure when we begin focus transaction, we prevent "scroll into
view".
3. `Focus` method of element/document stays unchanged, which by default
scroll into view if no parameter provided according to spec.
Testing: Manually tested on `servo.org` and other websites, and examples
with `<form>` still correctly scroll into view when validation fails.
