This is last step toward enabling the default rustc
`unsafe_op_in_unsafe_fn` warning for the script crate. It wraps the
remaining unsafe code in `unsafe {}` and removes the line disabling this
warning from `script`'s `Cargo.toml`. In addition, two variables are
renamed from `v` to something slightly more descriptive.
Testing: This should not change behavior so is covered by existing
tests.

We store a pointer to the ScriptThread singleton for a thread in
thread-local storage. While we don't have yet have profiles pointing to
this TLS access as a hot spot, we can remove a potential performance
footgun without a lot of effort by passing around small pieces of data
that we otherwise need to fetch from the ScriptThread.
Testing: Existing WPT is sufficient

Remove size bound from safe to jsval trait, apply to script/dom, with
the exception of windowproxy.

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.

These changes make our implementation of the enumeration hook for
globals [match
Gecko's](https://searchfox.org/mozilla-central/rev/1f65969e57c757146e3e548614b49d3a4168eeb8/dom/base/nsGlobalWindowInner.cpp#3297),
fixing an assertion failure that occurred in the previous
implementation.
Our enumeration hook is supposed to fill a vector with names of
properties on the global object without modifying the global in any way;
instead we were defining all of the missing webidl interfaces. We now do
much less work and crash less.
Testing: New crashtest based on manual testcase.

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.

Returning raw JSVal values makes it easier to create GC hazards in code

ensures that the values are rooted by the caller.

This change fixes all rustdoc errors and also adds a tidy check for a
very common rustdoc URL issue. Eventually rustdoc warnings should likely
cause the build to fail, but this catches those issues sooner in order
to not waste so much developer time.
