Add TransferImageBuffer message
https://bugs.webkit.org/show_bug.cgi?id=249111
<rdar://problem/103232081>
Reviewed by Kimmo Kinnunen.
This implements transfering the backend of a RemoteImageBuffer from its
existing RemoteRenderingBackend/WorkQueue to its new RRB.
This will likely be replaced in the future with the new way of sharing
resources in the GPUP.
When we create a new ImageBuffer in the WebProcess, and want to transfer
contents, we send the message across the connection for the
new buffer.
The GPUP side dispatches messages to the main thread to find the
RemoteRenderingBackend, dispatches to the existing WorkQueue to take
ownership of the old buffer and dispatches the result back to the new WorkQueue
to complete the transfer.
RemoteImageBuffer sends the same didCreateImageBufferBackend message back once
the buffer is transferred (as happens when a remote buffer
is allocated), so that WebProcess attempts to block and wait for the buffer to
be available succeed.
