VideoPlayer/LibVideo: Seek accurately when scrolling in the seek bar

Fast seeking does not work correctly when seeking in small increments,
so it is necessary to use accurate seeking when using certain actions.

The PlaybackManager has been changed to accept the seek mode as a
parameter to `seek_to_timestamp` to facilitate this. This now means
that it no longer has to track a seek mode preference.
