cc: Use HighResNow as timebase if it is fast and reliable
If base::TimeTicks::HighResNow is fast and reliable, we use it
for frame times, animations, and scheduling. Otherwise, we use
base::TimeTicks::Now and use a timebase of zero to avoid an
incorrect or jittery timebase.
This adds a gfx::FrameTime::Now() function, so the same timebase
is used across the ui and cc directories.
Additionally, the OutputSurface now uses a HighRes version of the
DelayBasedTimesource if gfx::FrameTime::Now() is HighRes.
