Fix non thread-safe usage of makeWeakPtr() in MediaPlayerPrivateAVFoundation
https://bugs.webkit.org/show_bug.cgi?id=199777

Reviewed by Eric Carlson.

The code was calling makeWeakPtr() on a main-thread object, from a background thread.
This is not thread safe. To address the issue, this patches creates the WeakPtr ahead
of time, on the main thread.
