Add an observer to restart the PVideoBridge connection when GPU process
restarts.

Combine sVideoBridgeToParentProcess and sVideoBridgeToGPUProcess into one
sVideoBridge. Each producing process, GPU or RDD, is only ever started with one
VideoBridgeChild endpoint. This is enough to get RemoteVideoDecoders in RDD
process to start using GPU memory to send video to compositor over PVideoBridge.

In the future we're going to want VideoBridge connections from the RDD process into both the parent process and the GPU process.
This does the preparation work for unifying the way we create VideoBridges (using Endpoints, required for cross-process connections),
and detects which one to use based on where the video will be composited.

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.
