Before Bug 1570869, new frame was generated if WR does not have a pending frame build task. But since Bug 1570869 fix, there is a case that new frame generation does not happen even when WR does not have a frame build task.

This makes it clear that these belong to a single frame and makes some assumptions explicit.
For example, in the old code, mDocFrameCounts.size() was the same as mPendingFrames.size()
when a pending frame was added, but then the sizes differed during rendering because a frame's
mDocFrameCount would be popped at the beginning of rendering while mPendingFrames would be
popped at the end of rendering.
This modification also makes some clearing of values unnecessary. A new frame always starts out
with cleared values for mDocFramesSeen and mFrameNeedsRender.
This patch also combines the two locks in HandleFrameOneDoc.

The only place that increments mRenderingCount, HandleFrameOneDoc, also synchronously calls FrameRenderingComplete
at the end of the function, which decrements mRenderingCount again. So it can never grow beyond 1.

IncRenderingFrame only had one caller. Inlining it into HandleFrame makes it clearer
how the values in mWindowInfos are mutated and in what order calls happen.
This also renames HandleFrame to HandleFrameOneDoc, because we're expecting one call
per document before we actually trigger the render.

Now that there is only ever a single handle to the `CompositionRecorder`, it no
longer needs to be ref-counted. And since the `WebRenderCompositionRecorder` is
owned exclusively by the `RenderThread`, it no longer needs a mutex. All the
code that resulted from having handles to the `WebRenderCompositionRecorder` on
two different threads is now no longer necessary.

On macOS, if we try to write the collected frames from the
`CompositorBridgeParent` we will not have an active GL context, resulting in a
crash. Writing the frames from the `RenderThread` solves this problem.

On android, android's nsWindow creates LayerManaer only in nsWindow::Create(). When WebRender error happened, gecko just stopped rendering by disabling Webrender.
The nsWindow needs to re-create LayerManager during disabling Webrender. Further, during disabling WebRender, All GeckoSurfaceTextures should not be attached to GLContext. It is for preventing a conflict with AttachToGLContext() call in SurfaceTextureHost::EnsureAttached().

Now that we have a suitable composition recorder infrastructure, it is just a
matter of plumbing the `WebRenderCompositionRecorder` from the
`CompositorBridgeParent` to the `RenderThread` to start recording frames.

BGRA may not be supported on GLES implementations, such as on the
Pixel 2 device. Since WR on Android uses GLES, we should use RGBA
when getting snapshots so that it actually works instead of failing
silently.

GeckoSurfaceTexture could bind to only one GL context at once. With WebRender, GeckoSurfaceTexture is soon bounded to sharedGL on render thread. It caused the problem if GeckoSurfaceTexture is rendered to WebGL. It could happen only for video's GeckoSurfaceTexture. To avoid the problem, the GeckoSurfaceTexture is bound to gl context when it is actually rendered on WebRender.

* Remove redundant virtual keywords
* Mark all destructors of inheriting classes as virtual for clarity
* Mark all classes without virtual destructor as final (exposed errors)
* Make destructor virtual where it needed to be (some were missing)
* Replace empty ({}) code declaration in header with = default
* Remove virtual unused methods
I probably missed some, it quickly became a rabbit hole.

When SurfaceTexture is single buffer mode, UpdateTexImage() should be called only once for each publish. If UpdateTexImage() is called more than once, it causes hand on puglish side.

Splitting part of OGLShaderProgram.h out into OGLShaderConfig.h makes it
easier to keep GLContext.h included in OGLShaderProgram.h for inlining
