This patch makes the remote canvas enabled state global. If we failed to
create a context, then it cannot recover, so we should never try again.
In the event of stream errors, it is likely due to virtual memory
shortages.

Current gecko enables "software decoded video overlay" only when "hardware decoded video overlay" is enabled. On current release, "hardware decoded video overlay" is not enabled yet with non-Intel GPU, then "software decoded video overlay" is not yet enabled on release. It is not good. We want to enable "software decoded video overlay" independently from "hardware decoded video overlay". Then settings of video overlay is split between "hardware decoded video overlay" and "software decoded video overlay". Then "software decoded video overlay" could be enabled/disabled independently from status of "hardware decoded video overlay".

Fallback from SW-WR + OpenGL to SW-WR is not implemented yet. Since the fallback is not expected to be used on release.
Fallback implementation is borrowed from the fallback process of "WebRender + D3D11" and gfxVars::AllowSoftwareWebRenderD3D11() handling.

Bug 1704954 disabled DirectComposition for users with NVIDIA graphics
hardware and mixed monitor refresh rates on Windows 10 and 11, as a
mitigation for bug 1638709. However, that bug is almost -- perhaps
entirely -- unknown on Windows 11 (q.v. for details), and the fallback
path it uses has been shown to cause issues there (bug 1763981).
Restrict the mitigation to only occur on Windows 10, where bug 1638709
is exhibited, but where no issues with the fallback path are known.
This also effectively reverts bug 1816001, which it obviates.

- Add H264_HW_DECODE / AV1_HW_DECODE features to track H264/AV1 decoding state on Linux.
- Add UseH264HwDecode / UseAV1HwDecode gfx variables to route decode state to RDD process.
- Init H264_HW_DECODE / AV1_HW_DECODE features on Linux only and skip all HW decoding features init if VA-API is not supported.

This mitigation exposed bug 1763981. Unfortunately, not applying it on
Nightly made it look like bug 1763981 was _fixed_ in Nightly, tricking
several users and developers and making testing needlessly more
difficult even after this was discovered.
Apply the mitigation across the board, regardless of release channel.
Developers may still set `gfx.webrender.dcomp-apply-1704954` to override
this as needed for testing (e.g.) fixes for bug 1638709.

This patch adds two new prefs, gfx.webrender.scissored-cache-clears
.enabled and .force-enabled to control its status beyond the blocklist.
The former is true by default and allows one to turn the feature off by
flipping it to false. The latter allows one to force the feature on even
if the blocklist disables it. It also adds the status to the decision
log in about:support.

Bug 1638709 describes artifacts when the webrender compositor is enabled
on certain Windows systems with NVIDIA cards and mixed monitor refresh
rates. As of bug 1704954, we currently disable DirectComposition on such
systems in Beta and Release as a mitigation.
Unfortunately, on a significant (albeit not yet fully characterized)
fraction of Windows 11 machines, the fallback compositor also has
issues, resulting in bug 1763981 (clipping of web content on first
entering fullscreen). Users experiencing this latter issue have hitherto
_not_ reported the former when testing on Nightly, suggesting that the
mitigation may be getting applied overbroadly.
Add a pref to allow disabling the mitigation in question, so that users
experiencing bug 1763981, but who are not subject to 1638709, have a
less intrusive workaround than remembering to hit F11 twice every time
they start Firefox.

Modify AHardwareBuffer implementation as to support gl::SharedSurface of out-of-process WebGL. And remove unused AHardwareBuffer implementation.
By limiting AHardwareBuffer only in GPU process, AHardwareBuffer implementation becomes simpler. We do not need to handle cross process AHardwareBuffer delivery and cross process android Fence delivery.

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.
