  [Cocoa] Plumb a video receiver endpoint from LinearMediaPlayer to MediaPlayerPrivate
https://bugs.webkit.org/show_bug.cgi?id=269490
rdar://123028396

Reviewed by Jer Noble.

To support entity-based rendering in LinearMediaPlayer, we must pass a video receiver endpoint from
LinearMediaPlayer to MediaPlayerPrivate so that it can be added as a target to AVPlayers and
AVSampleBufferVideoRenderers in the GPU process. This PR adds that plumbing (but saves actually
attaching the endpoint to AVFoundation objects for a later PR).

Note that a video receiver endpoint object contains an xpc_endpoint_t, which is not a type we can serialize in CoreIPC.
Like we do for other xpc_endpoint_ts, this PR sends it directly over the XPC connection from the UI
process to the GPU process.
