6c334f2811 script: Replace RAII of CallSetup and AutoEntryScript with a function wrapper (#42715)
As mentioned in #40600 we will need this to properly handle &mut
JSContext (we cannot pass it to drop) and I think this wrappers are
preferred ways of doing this in rust as it is safe to forget (not call
drop) which is unsound in this case (due to realm stack at least).

Revieable per commits.

Testing: Just a refactor, but should be covered by WPT

3047b9946f script: Remove AsVoidPtr and AsCCharPtrPtr traits (#42153)
We migrated most uses some years ago, so let's finally remove them. It's
more clear what we are doing if we inline stuff then hiding dangerous
cast behind trait.

Testing: Covered by WPT, try run:

f13b8e6ed5 chore: suppress warnings when building without the testbinding feature (#42003)
When building without the `testbinding` feature of `libservo`, we end up
with these compilation warnings (and one error):

d86d2a90aa script: Use rooted typed arrays in generated code and buffer source APIs (#41228)
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.
Fixes: #41206

56d9e24bff script: Implement import key operation of RSA-PSS (#41157)
Start adding RSA-PSS support to WebCrypto API.

This patch implements import key operation of RSA-PSS, with `rsa` crate.

Testing:
- Pass some WPT tests that were expected to fail.
- Some new FAIL expectations are added. They were skipped by WPT when
the import key operation of RSA-PSS had not been implemented, and
requires other not-yet-implemented operations to pass.

Fixes: #34362, and part of #41113

c27f8c565a Use safe JSContext/AutoRealm/CurrentRealm in codegen (#40716)
We replace many places that use `SafeJSContext` with `JSContext` and I
also rewrote `is_platform_object_same_origin` to use new `JSContext`.
Unfortunately using wrappers2 in them causes crashes (in handle code),
so I reverted that part in last commit and will fix handles in mozjs
later.

Testing: Refactor, but it is covered by WPT tests
Part of #40600

fa12f7a5e5 script: Add cx_no_gc/cx/realm codegen option and demostrate them (#40582)
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.

next steps: #40600

6f53d422b0 Make ImageData more spec compliant (#37620)
I updated webidl, and all changes that bring, currently we still not
support float16array (there is no support in FF either). Most notable
change is refactored new_*/Constructors methods, that should now handle
HeapBufferSource more properly (with less unsafe).

Testing: Existing WPT tests
try run: https://github.com/sagudev/servo/actions/runs/15806083404
Fixes: #37618 (although not tested)

c37d5572fd codegen: use FromJSValConvertible trait for Promise (#36966)
Before it was only used when converting to a `Record`, using it all the
times allow us to remove two methods.
Plus added a helper method in CodegenRust.py to avoid repeated code.

Testing: a successful build and existing tests should cover the changes.
Fixes: #36410

76ee127af8 Eagerly define interfaces on non-Window globals (#36604)
These changes make us match Gecko's setup for how Window and non-Window
globals are initialized. Since Window globals are much more common than
Worker globals, using lazy interface definitions can be a useful memory
optimization at the expense of increased complexity for property
lookups.

Also adds the MayResolve hook for all globals, which is an optimization
for the JIT to avoid calling resolve hooks unnecessarily.

Testing: Existing test coverage on global interfaces should suffice.

b4079b3ff3 Move generated bindings to script_bindings (#36323)
This is the final step of #1799, where the majority of the generated
code for the JS bindings is now compiled as part of the script_bindings
build step. The remaining pieces in script must live there because they
refer to concrete DOM types; all code in script_bindings is generic over
the
[DomTypes](https://doc.servo.org/script/dom/bindings/codegen/DomTypes/trait.DomTypes.html)
trait.

My testing with incremental builds shows me a 12 second reduction in
build times on my 2024 M4 Macbook Pro when modifying code in the script
crate after these changes. Before this PR those changes took 20 seconds
to rebuild Servo, and now they take 8 seconds.

Testing: Existing WPT tests ensure no regressions.
Fixes: #1799
