QMediaPlayer: handle resource files in a cross-platform way.

It was the backend's responsibility to handle resource files in an
appropriate way. In practice, it was either not handled at all,
or implemented in an almost identical manner in every backend
that does handle it.
This is now dealt with in QMediaPlayer, always passing to the
backend something it will be able to play. If the backend has the
StreamPlayback capability, we pass a QFile from which it streams
the data. If it doesn't, we copy the resource to a temporary
file and pass its path to the backend.
