Add ability to specify delayed task precision in RepeatingTaskHandle.

Browse Source 
See go/postdelayedtask-precision-in-webrtc for context of which use
cases are considered "high" or "low". Most use cases are "low" which
is the default, but this CL allows opting in to "high".

Will be used by FrameBuffer2.
