gpu: Remove Create/DeleteImage IPC by adding an X11_PIXMAP_BUFFER GpuMemoryBuffer type.

This adds a new GpuMemoryBuffer type that can be used to create
a GpuMemoryBuffer from an existing X11 pixmap.

This removes Create/DeleteImage IPC and reduces complexity
significantly as it allows the ImageManager to be moved to
the decoder and simply track images.

A new platform dependent GpuMemoryBufferFactory interface
is introduced to allow this new type of buffer to be created
on the GPU service side. To avoid the need for any global
variables, this factory instance is also responsible for
creating GLImage instances.

The old factory interface used by android_webview is renamed
InProcessGpuMemoryBufferFactory until it can be removed in
favor of this new interface.
