This patch integrates OffscreenCanvasDisplayHelper with
HTMLCanvasElement, OffscreenCanvas and nsDisplayCanvas to allow
asynchronous display of an OffscreenCanvas.

Workers require all runnables to implement nsIDiscardableRunnable. This
is because the worker may want to terminate after going out of scope,
and want to discard any pending events. It should be safe to simply drop
any WebGL related events since we are going to tear down the context /
actors as well.
Also ensure that we record dirty events even without an associated
HTMLCanvasElement so that the OffscreenCanvas is notified properly.

For WebGL canvases with preserveDrawingBuffer:false, frontbuffer
snapshotting was not working properly.
If the frontbuffer had no user-fb associated with it,
was inexplicably calling BindDefaultFBForRead, which binds
*webgl*'s default FB, not *gl*'s default FB 0.
This caused frontbuffer snappshotting to actually snapshot the (cleared)
backbuffer instead of the visible frontbuffer contents.

Currently we return an error when creating a WebGL context in headless
mode, but our WebGL implementation renders to an offscreen context, so
in theory it could work normally in a headless browser, and in practice
it already does work on some OSes. This patch removes that check; the
attempt to use GL may fail, in which case we'll return an error to
content.
The main purpose of this patch is to run content processes with headless
mode set in an otherwise non-headless browser, but it should also be
useful for fully headless mode. Comments in bug NNNNNNN indicate that
this change should be sufficient for headless WebGL on Windows and MacOS,
although it may not have been extensively tested.
Linux is more complicated. The EGL/X11 backend manages its own
connection to the X server (indirectly via the EGL library); a later
patch in this series allows doing that in GLX mode as well. Our Wayland
support can't do this yet, but it should be possible.
This patch also modifies the Linux sandbox policy so that content
processes can connect to a local X server (via the file broker) even when
the parent process is in headless mode.

Previously we called GetFrontBufferSize, alloc'd a buffer, and called
FrontBufferSnapshotInto to read into the buffer.
Now, call FrontBufferSnapshotInto({}) to get size, and then alloc and
pass pointer to newly alloc'd data into
FrontBufferSnapshotInto(Some(ptr)).
Using the same function for both means that logic can't diverge and
cause mismatch bugs.

* Use clearer pref names.
* Default (and only support) IPDL dispatching.
* Make DispatchCommands async-only.
* Sync ipdl command per sync webgl entrypoint.
* Eat the boilerplate cost, since there's not too many.
* Run SerializedSize off same path as Serialize.
* All shmem uploads go through normal DispatchCommands.
* Defer pruning of dead code for now so we can iterate quickly.
* Use Read/Write(begin,end) instead of (begin,size).
* This would have prevented a bug where we read/wrote N*sizeof(T)*sizeof(T).

Splits WebGLContext into ClientWebGLContext and HostWebGLContext. The Client enables the JS-control of a WebGL context in a content procecss while the Host executes the WebGL graphics operations (via a WebGLContext that maintains much of the existing code) in the compositor process. At this point, the cross-process behavior is disabled -- this series of patches is an incremental step toward that final goal.

When JS is paused, VRService will automatically shutdown because the timer is not updated,
we used to create a new VRDisplay to JS. However, the page is still using the older VRDisplay,
so it can't get the newest VRDisplayInfo status. We should exit presentation and
apply the VRDisplayInfo status to the original VRDisplay instead of creating new one.
Besides, we also need to release the VR screen buffer after exiting the immersive mode to avoid eglMakeCurrent error.
