[Modern Media Controls] Add rewind and fast-forward support
https://bugs.webkit.org/show_bug.cgi?id=165294

Reviewed by Dean Jackson.

We implement support for rewinding and fast-forwarding the media by pressing dedicated
buttons in fullscreen on macOS. We introduce a new SeekButton class that the existing
RewindButton and ForwardButton classes now extend and which provides handling of
"mousedown" and "mouseup" events to indicate that a button is being pressed to the
UI delegate.

We also introduce a new SeekSupport class from which SeekBackwardSupport and
SeekForwardSupport inherit to integrate with those controls and update the media
time.
