<!-- Please describe your changes on the following line: -->
This is marked as WIP because with these functions added (but apparently not directly related to them), some tests now run into states that produces crash.

Add support for launching devtools server on random port
In case the default port(6000) or the port specified by user for
devtools server is already taken, random port will be assigned to
it which is reported to the embedding layer for display to user.

layout_2020: Paint hoisted positioned fragments in tree order
Instead of painting hoisted position fragments in the order to which
they are hoisted, paint them in tree order and properly incorporate them
into the stacking context.
We do this by creating a placeholder fragment in the original tree position
of hoisted fragments. The ghost fragment contains an atomic id which
links back to the hoisted fragment in the containing block.
While building the stacking context, we keep track of containing blocks
and their children. When encountering a placeholder fragment we look at
the containing block's hoisted children in order to properly paint the
hoisted fragment.
One notable design modification in this change is that hoisted fragments
no longer need an AnonymousFragment as their parent. Instead they are
now direct children of the fragment that establishes their containing block.

Add VertexArrayObject support for WebGL2
The implementation was already in place for OpenGL ES.
My approach with this patch is to add support for WebGL2 by
sharing the implementation between the WebGL2 and GLES.
Sadly I couldn't manage to place the WebGL2 and OpenGL ES variant to the same slot in `WebGLRenderingContext`, therefore I had to do same code duplication.
Fixes#25956.

Remove XR canvas dirtying step.
Alan tells me that this is no longer necessary, and it causes layout operations to appear in immersive mode profiles when there should not be any.
Remove GL->d3d blit in HoloLens immersive mode
Depends on:
* https://github.com/servo/surfman/pull/151
* https://github.com/asajeffrey/surfman-chains/pull/7
* https://github.com/servo/webxr/pull/133
These changes add two extra APIs for embedders to use when registering a WebXR device - one to allow running any closure as a task in the webgl thread, and one to register an arbitrary surface provider for a particular webxr session. When an openxr session is started, it can then obtain the webgl thread's d3d device from that thread's surfman device and ensure that openxr uses it.
Surface providers are traits that have their methods invoked by the webgl thread as part of the the normal swapchain operations. This allows the openxr surface provider to return surfaces that wrap the underlying openxr textures, which are valid in the webgl thread and can be used as the target of an opaque framebuffer.

Add VTTRegion and part of VTTCue DOM interfaces
<!-- Please describe your changes on the following line: -->
Hello! In this PR I implemented the VTTRegion DOM interface and part of VTTCue (#22312). Before continuing I thought it's maybe a good idea to first request a review or even merge what I did up to this point, as I might get stuck on the next part. I have a slight idea of what needs to be done (I assume it's hooking the GStreamer parser somewhere in `GetCueAsHTML()`), but a short outline or some more instructions would help a lot.
I updated test expectations by first running:
```
./mach test-wpt tests/wpt/web-platform-tests/webvtt/api --log-raw servo.log --pref dom.webvtt.enabled=true
```
then
```
./mach update-wpt servo.log
```
Thanks!
