Add support for overflow:scroll and overflow:hidden to layout_2020
This adds clipping and interactive scrolling support, but scrolling from
script is still not functional.

Do not include request progress/total values on XHR timeout
<!-- Please describe your changes on the following line: -->
Do not include request progress/total values on XHR timeout as [the specification]( https://xhr.spec.whatwg.org/#request-error-steps) states that upload events when errors occur should always pass 0 for both values.

Kill off hanging crashtests.
The reason that complex-glsl-does-not-crash.html kept leaving zombie processes is the following:
* WPT introduced the notion of crash tests (ie. tests that verify that they do not crash)
* if a timeout expires while running a crash test and the test has not finished running, it is reported as a failure and potential hang
* there is no code that causes a hanging test to stop running
* any test filename that ends in `-crash` is automatically treated as a crashtest
Try to avoid panicking during I/O in the signal and panic handlers.
A bunch of mac WPT processes are sitting in zombie states where a thread has hit a double panic while printing the backtrace. These changes attempt to prevent this issue by ignoring any I/O failures that occur while printing, instead of panicking.

Implement SubmitEvent
<!-- Please describe your changes on the following line: -->
FormSubmitter was already being passed into submit, so there wasn't much work to do here other than making the new event interface itself.

fix DOMTokenList
I fixed the bug described in 25128, and also the other cases in the same test (order of elements after replace).

Implement :defined CSS selector
<!-- Please describe your changes on the following line: -->
ElementState::IN_DEFINED_STATE already existed but wasn't hooked up to anything; now it is set appropriately, and CSS is aware of it. The main test for this selector needed the window named getter for no important reason, so I made a one-line test change to avoid that. Remaining failures in the test are all about SVG elements.

Make nulling out an inline event handler remove it from the list order
Setting a content attribute or IDL attribute to null now removes event handlers like it's supposed to; the removeAttribute case seems to be something deeper which this change doesn't fix.

Send request's integrity metadata via RequestBuilder
RequestBuilder wasn't reinflating integrity_metadata along with other request fields, so main_fetch never saw that an integrity checksum was requested. Integrity checking seems to have otherwise been working; with this change, the entire WPT test for it passes (other than the SharedWorker test, which would probably pass if we had SharedWorker)

Initial implementation of GPUBindGroup for WebGPU
Added WebIDL bindings for `GPUBindGroup`.
Implemented the `createBindGroup` function of `GPUDevice`
Renamed `GPUBindGroupBinding` to `GPUBindGroupBindings` and `GPUBufferBinding` to `GPUBufferBindings` in the WebIDL, because these names are already occupied.

move ConstellationMsg to compositing
<!-- Please describe your changes on the following line: -->
`ConstellationMsg` enum in script_traits is moved to compositing since it's not used by script_traits. The other enums mentioned in the issue, `LayoutControllerMsg` and `LayoutMsg` cannot be moved out of script_traits since script_traits depends on both of them and moving out would create cyclic dependencies.

Enable Mozilla CSS tests for layout_2020 and add expectations
This change allows mach to run the Mozilla CSS tests when running with the ``--layout2020` argument. This is useful because we can mark tests as passing as features are added.

Remove unnecessary LocalName::from(constant) calls
Changing calls to LocalName::from with a constant argument to use the interned local name instead doesn't really save a meaningful amount of time (when it's not in a loop or on a critical path), but it's good for codebase consistency.
Implement URLMismatchError
Nothing in current specifications actually throws this DOMException type, but the type exists in specs nonetheless, and adding it lets us check off a WPT test.

Make error events only pass the extra error-event arguments to global listeners
Error event handlers were getting lineno, etc. arguments even when they weren't on globals, failing two WPT tests; this fixes that.

Add profilemozjs feature to embedding
This makes it possible to obtain better profiling output from the JS engine when building for an embedder like the HoloLens.
