Add a simple implementation of CanvasRenderingContext2d.fillText
<!-- Please describe your changes on the following line: -->
I added a simple implementation of CanvasRenderingContext2d.fillText.
Some code are merged from @mikrut, and I fixed a bug about text scaling.
Also, the bug of text rotation should be fixed after `raqote` merged my other PR.

Don't run 2dcontext tests in layout-2020.
The vast majority of these tests only test the DOM APIs, not the actual layout via reftests. That means we just duplicate the results and have to update them every time we change the canvas behaviour.
Add support for tracking containing blocks when doing inline layout.
This requires setting up a PositioningContext for inline boxes when
necessary. Instead of using the PositioningContext helper methods
and we reuse the contexts between line breaks.
Fixes#25279.
Do not try to read pixels from an FBO without read buffer
A follow up to #25905, this adds another check to the WebGL2 ReadPixels implementation to fix
an OpenGL invalid operation crash when the method is called on a bound framebuffer that has no read buffer.
<!-- Please describe your changes on the following line: -->

However, it seems there's an issue with the headless mode: when ReadBuffer is called on the default framebuffer with the value `GL_BACK`, like [here](e1103176e3/tests/wpt/webgl/tests/conformance2/renderbuffers/readbuffer.html (L77)), in headless mode an invalid operation is generated. In non-headless mode the whole test completes successfully:

Add support for WebGL2 read and draw buffer settings
Adds support for the `ReadBuffer` and `DrawBuffers` WebGL2 calls and the related parameter getters.

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.

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 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.
