The remote texture is processed asynchronously, but the WebGL rendering results are rendered synchronously with WebRender transaction by WebRender.
Async remote texture support is enabled only when CanvasRenderThread is used. This is to simplify implementation.
In async mode, remote texture of current RemoteTextureId might not be created yet when WebRenderImageHost::UseRemoteTexture() is called. In this case, RemoteTextureHostWrapper uses its own external image ID, otherwise the RemoteTextureHostWrapper uses compatible old remote texture for creating wr display list. RenderTextureHostWrapper calls RemoteTextureMap::GetExternalImageIdOfRemoteTextureSync() before is ussage. The GetExternalImageIdOfRemoteTextureSync() synchronously waits until remote texture becomes ready. The wait works since WebGL IPC handling is always done in CanvasRenderThread in async mode.
PWebGLChild::SendGetFrontBuffer() triggers sync IPC. It is called to ensure the compatible remote texture in RemoteTextureMap during RemoteTextureMap::GetRemoteTextureForDisplayList() call.

We used to provide links to the bug numbers but this was broken
somewhere along the way. Now it is provided the failure IDs from which
it can attempt to extract a bug number, as well as always display any
failure ID and message whenever possible.

WebRender is a mature feature. We should start blocking it on known bad
devices over allowlisting known good devices. This may enable WebRender
in a few more obscure places than we shipped before.

With CI's NVIDIA GPU, SharedHandle of ID3D11Texture2D of hardware decoded video during no video copy caused rendering problem. When SharedHandle is not used, the rendering problem did not happen. But when video is rendered to WebGL texture, SharedHandle need to be used.
In this case, D3D11TextureIMFSampleImage copies original ID3D11Texture2D to a new ID3D11Texture2D and use a shared handled of the copied texture. And no video copy of future video frames are disabled.
NoCopyNV12Texture is renamed to ZeroCopyNV12Texture to clarify its meaning.

This patch just adds the plumbing to allow for baked in blocklist rules
or the downloadable blocklist to prevent certain configurations from
getting WebGPU. It does not add any rules.
It also changes us from allowing WebGPU only in nightly, including
tests, to not release and not beta. This allows try to run the WebGPU
tests as expected, since even try builds forked from mozilla-central are
not considered nightly builds by CI (or so it seems).

This patch adds several new prefs to control what happens with
OffscreenCanvas. gfx.offscreencanvas.enabled works as it did before.
- gfx.offscreencanvas.domain-enabled: Enables OffscreenCanvas for
domains on the allowlist.
- gfx.offscreencanvas.domain-allowlist: Comma separated allowlist
which controls which domains can access the OffscreenCanvas constructor
and HTMLCanvasElement.transferControlToOffscreen.
- dom.workers.requestAnimation: Controls whether or not
request/cancelAnimationFrame are accessible from dedicated workers.
Ideally this would have used the same decision process as
OffscreenCanvas but there were unrelated build/runtime issues around
using a Func directive with DedicatedWorkerGlobalScope.

If GL is threadsafe, we can run on the compositor thread. This appears
to have performance benefits, possibly because the renderer thread is
too busy. If GL is not threadsafe, we must run the WebGL OOP instances
on the renderer thread.
At the time of writing, only the nouveau drivers on Linux are considered
to be not threadsafe, so most users will see WebGL running on the
compositor thread. This patch also adds prefers to override the
blocklist to either assume GL is threadsafe
(webgl.threadsafe-gl.force-enabled) and not threadsafe
(webgl.threadsafe-gl.force-disabled).

The default size on most platforms is 256*256 which corresponds to the default blob tile size. I didn't check on android so I set it to 512*512 above which we never batch the upload so that the behavior is unchanged, but I suspect that a smaller threshold like 256*256 would also work better there.
On Windows with heavy blob image workloads, not batching gives a 20%-30% improvement to the time spent in update_texture_cache.

Right now adding a dynamic pref for webrender involves plumbing in gfxPlatform, gfxVars, CompositBridgeParent, WebRenderBridgeParent, WebRenderAPI, the bindings, and then messaging the pref change to the right thread in WebRender.
That's quite a bit time consuming for something we tend to do for multiple things.
We already have a pretty good system for boolean debug prefs where the pref only needs to be listed in gfxPlatform and in the DebugPref enum of webrender_api/lib.rs, which has led us to use it for non-debug purposes.
This patch adds a system similar to the DebugFlags with values passed in a bitfield to be able to use gfxVars. In WebRender the parameters are key-value pairs which flow through the pipeline so that any component can react to them. A followup will add integer parameters.
The patch also moves a few prefs to this system and adds a pref to use PBO uploads.

The prefs name is gfx.webrender.blob-tile-size and can be changed at runtime.
It changes the behavior of a wrench reftest that was ensuring that we don't crash with unreasonable tile sizes. The new behavior (sanitizing the tile size) means we can render the image while we would previously skip it.
