This commit remove more unused code from `script_module`,
`inline_module_map` and `dynamic_modules` fields from `GlobalScope` and
the now unused custom interface `DynamicModuleOwner`.
Testing: No functional change, a successful build is enough.

This replaces uses of our custom RootedVec type that were storing JS GC
values with stack rooting that is better integrated with the engine.
This ensures that storing nursery-allocated objects in these vectors is
handled correctly during GC, unlike our RootedVec implementation which
trips an assertion in debug mozjs builds.
Testing: No observable difference in non-mozjs builds.

Add an event listener for `pause` to `debugger.js` and the necessary
glue to access it from the `devtools` crate. This returns important
information to know where we are paused, such as the source location and
frame state.
Fix frame and object actor encoding into messages. Use information from
`debugger.js` to correctly fill the fields.
Add a new `frames` list to the thread actor and handle the `frames`
message.
Fix `getEnvironment` reply in the frame actor. It is out of form (has a
`type` field but it doesn't require a followup empty message, it already
counts as a reply), so we need to handle it specially.
Note: For now we are focusing on the protocol side of the debugger, and
this patch only shows where the pause would happen. Pausing Servo itself
will happen in a followup.
Testing: `mach test-devtools` and manual testing. No errors (apart from
#42006).

At the start of the script we create first (and only[^1]) safe
`JSContext`, from where we should pass it down to every code that needs
the cx. This PR brings it all the way down to message handlers. There is
clear separation between functions that use new model `&mut JSContext`
and the ones that use the old model (usually they take can_gc).
[^1]: Another place of construction are SM hooks (that pass us down raw
JSContext), but to reach that point we already needed to call another
function that takes `&mut JSContext`, so one can look at this case as
reentering/reborrowing (we derive new shorter `&mut JSContext` from the
old one).
Testing: This is just refactor, but should covered by WPT tests.

Add placeholder implementation of DOM `VisualViewport` according to the
spec https://drafts.csswg.org/cssom-view/#visualviewport. This is the
first step of implementing the interface and syncing it with the
`PinchZoom` struct that we had in the `Embedder`.
Since this interface's is not accurate and couldn't fulfill it's
purpose, it would be gated behind a preference
`dom_visual_viewport_enabled` and would be open after the interface had
been integrated with `PinchZoom`, viewport resizing, and viewport
scroll.

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 the solution from #26488 that prevents implementing Drop
manually for DOM interfaces, which is very easy to write in a way that
can cause memory safety errors during JS runtime teardown. Since we have
a bunch of pre-existing implementations that we are working on removing,
this PR adds an opt-out mechanism that those interfaces use.

The media session is allowed to control the state of the media element
(play, pause) and is holding DOM reference, so the latest registered
media element is not be able to be GCed, so let's use the weak reference
to break this dependency.
Note that `weakReference` property was added to interfaces
- HTMLMediaElement: The `Mutable/WeakRef` requires T to be bound by
`WeakReferenceable`
- HTMLAudio/VideoElement: The `DOM_WEAK_SLOT` must be reserved by
concrete DOM JS class
Testing: No expected testing results changes
The media session UI functionality is implemented for Android and didn't

This web API is alternative API to `throw e`, which is why we can reuse
a lot of the existing machinery.
The one testcase that isn't passing yet is because it reports an empty
`TypeError`. The current logic in `ErrorInfo` only retrieves the message
data, but doesn't include the type of the exception. For that, we need
to use `(*report)._base.errorNumber` and map that back to the original
type codes. However, deferring that to a follow-up as that requires some
more work in mozjs.

Companion to https://github.com/servo/mozjs/pull/650
We added 3 new options to bindings.conf, each more powerful then the
previous one, so one should use the least powerful as possible to keep
things flexible:
1 `cx_no_gc` prepends argument `&JSContext`, which allows creating NoGC
tokens and using functions that do not trigger GC.
2. `cx` prepends argument `&mut JSContext`, which allows everything that
previous one allows, but it also allows calling GC triggering functions.
3. `realm` prepends argument `&mut CurrentRealm`, which can be deref_mut
to `&mut JSContext` (so it can do everything that previous can), but it
also ensures that there is current entered realm, which can be used for
creation of InRealm.

The `seek` method isn't explicitly exposed in the API, but is called
from various places (`currentTime`, `fastSeek`, by the `media metadata`
event) and doesn't itself create new DOM objects, so the `canGC`
argument can be omitted.
It was previously required because calling the `Seekable` method creates
a new `TimeRanges` object, but it will now be replaced by the internal
`seekable` method to avoid interaction with the JavaScript engine (and
potential garbage collector).
The `earlyest possible position` method has been changed to match the
specification and use `seekable` instead of `played`. See
