Implement the `SubtleCrypto.supports` method in our WebCrypto API. The
*check support for an algorithm* algorithm is also implemented to
support the functionality of the `SubtleCrypto.supports` method.
The `SubtleCrypto.supports` method has two overloads. One of them has a
union containing a non-object value at the distinguishing index. Our
`codegen.py` currently does not support unions of non-object values at
distinguish index. So, `codegen.py` is also patched to extend its
support to unions of objects, strings, numbers and boolean values.
Specification of `SubtleCrypto.supports`:
https://wicg.github.io/webcrypto-modern-algos/#SubtleCrypto-method-supports
Specification of "check support for an algorithm":
https://wicg.github.io/webcrypto-modern-algos/#dfn-check-support-for-algorithm
Testing:
- Pass WPT tests related to `supports` method.
- Add new tests for IDL operation overloading with unions of various
types.

This method is the same as `DOMString::from` with a `String` argument
and `From` and `Into` are preferred when writing modern Rust.
Testing: This should not change behavior and is thus covered by existing
tests.

These three methods date back from the very early history of Servo and
are no longer necessary:
1. `Window.debug`: `console.log` is a better replacement for this method
now. A manual test that tests the very basics of JavaScript used
this. This test is removed as well.
2. `Window.gc`: This can be replaced with `TestUtils.gc`, which is part
of a W3C specification.
3. `Window.js_backtrace`: This method is moved to `ServoTestUtils`.
Testing: Tests are updated to reflect these changes.

This introduces a new `ServoTestUtils` namespace with a `forceLayout()`
function. This `forceLayout()` function returns an object which
currently has an array of the phases ran by layout. Also moves
`panic()`, `crashHard()` and `advanceClock()` from `TestBinding` to this
new namespace. `TestBinding` is meant to test the bindings generation,
but these are more generic helpers for Servo-only tests.
Testing: This change adds a series of Servo-only tests that verify the
behavior of the new `forceLayout()` function. Tests that rely on the
moved interfaces are updated and should continue to pass.

#42681 did not actually allowed using cx in Constructor, but it did most
heavy lifting. Now we need to pass cx to Constructor call (and skip
CanGc) if cx is requested in Bindings.conf. This PR also test this on
testbindings.
Also we now always use `let cx = &mut cx`, so we can always use just cx
(compiler will automatically deref it into &cx if needed). This is
important because codegen stuff is called from many places to it make
sense/easier to just unify this.
Testing: It compiles

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.

There are two flavours of the mozjs `TypedArray<T>` wrapper for typed
array objects: one stores a `Box<Heap<*mut JSObject>>`, while the other
just has a bare `*mut JSObject`. The second one must only be stored
inside the `CustomAutoRoot` rooting values, but we were using it in many
other places like WebIDL dictionaries without rooting it safely. These
changes make our typed array APIs always use
`RootedTraceableBox<TypedArray<T>>` with the `Box<Heap<*mut JSObject>>`
flavour, which ensures that the JS object stored inside the typed array
wrapper is always visible to the SpiderMonkey GC.
Testing: Adds a new test that crashes without these changes.

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 updates all Rc that were ignored for malloc_size_of to use
conditional_malloc_size_of, unless the type in the Rc itself doesn't
support malloc_size.
Regular expressions used to search for all occurrences:
```
ignore_malloc_size_of = "Rc.*"
ignore_malloc_size_of = "Arc.*"
```
There are a couple left since they have nested Rc, which I don't know
how to fix.
To be able to define these, several new implementations were added to
`malloc_size_of/lib.rs` as well as
`HashMapTracedValues`.
Testing: if it compiles, it's safe
