Disable SkiaGL on WebRender, since there is a case that R8G8B8X8 is used, but WebRender does not support R8G8B8X8 yet. And SkiaGL is already disabled by Bug 1468801.

This changes the lifecycle and API for TextureReadLock to fix file descriptor exhaustion
crashes. These changes are partially superficial and mostly align the API of TextureReadLocks
with their actual usage.
The changes are:
1. Create the TextureReadLock in the TextureClient constructor so it's available before IPC creation
a. This is superficial as EnableReadLock was always called before IPC creation
2. Send the ReadLockDescriptor in the PTextureConstructor message and close the file handle
3. Receive the ReadLockDescriptor in TextureHost and close the file handle
4. Send a boolean flag in layer transactions if the texture is read locked instead of a descriptor
5. Use a boolean flag in TextureHost to determine if the ReadLock must be unlocked instead of a nullptr
I believe that we can remove the InitReadLocks code from LayerTransaction as that was added to
prevent file descriptor limits in IPDL messages and is no longer needed with this change. But
that is a non-essential change and this patch is already big enough.

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

- This patch is the same as one from Bug 1382104 (Remove IsMirror concept
in favor of checking forwarder).
- It is safe to uplift this patch without the rest of Bug 1382104 as long
as the remaining Bug 1381084 is also uplifted.

This patch move common canvas interfaces out of layer. So I create a
base class CanvasRenderer which move interfaces from CanvasLayer.
CopyableCanvasRenderer from CopyableCanvasLayer, ClientCanvasRenderer
from ClientCanvasLayer and WebRenderCanvasRenderer from
WebRenderCanvasLayer. And finally, WebRenderCanvasRendererSync for the
non layers free mode and WebRenderCanvasRendererAsync for the layers
free mode.
Summary all changes in this patch.
* Move class CanvasLayer::Data to CanvasRenderer.h and rename it to
CanvasInitializeData. Because this class not only use by layer but also
* Move BasicCanvasLayer::UpdateSurface to
CopyableCanvasRenderer::ReadbackSurface.
* CanvasClient::Update now accepts ShareableCanvasRenderer as parameter.
not CanvasLayer.
use by layers-free mode. Move it out of layer's class makes more sense.
* Add InitializeCanvasRenderer in the canvas related classes to
initialize CanvasRenderer without involved layer.
* All canvas layer has function "CreateCanvasRendererInternal" that
initialize corresponding CanvasRenderer.
* Description of all CanvasRenderer classes:
** CanvasRenderer: Based classes.
** CopyableCanvasRenderer: Can readback canvas content to a
SourceSurface. Use by BasicCanvasLayer.
** ShareableCanvasRenderer: Provide IPC capabilities that allow sending
canvas content over IPC. This is pure virtual class because the IPC handling is
different in different LayerManager.
** ClientCanvasRenderer: Implement IPC handling for ClientLayerManager.
Use by ClientCanvasLayer.
** WebRenderCanvasRenderer: Implement IPC handling for
WebRenderLayerManager.
** WebRenderCanvasRendererSync: Use by WebRenderCanvasLayer.
** WebRenderCanvasRendererAsync: Use by layers-free mode in WebRender.

- When a canvas layer is set to mirror, it copies the
texture from the canvas rather than changing the
texture factory with Morph().
- This is useful when a canvas content will be sent to
multiple devices simultaneously, such as a VR HMD
and a 2d monitor mirror.
- This is used by the WebVR 1.0 API, in Bug 1250244

- Generate and pass sequential frame indexes into the ovr_GetTrackingState call and the corresponding call to ovr_SubmitFrame
