Reland "SF: Encapsulate frame targeting"
Introduce FrameTargeter to isolate a display's per-frame metrics around
past/upcoming deadline targets. The Scheduler updates the FrameTargeter
on frame begin/end, whereas ICompositor (concretely SurfaceFlinger) has
read-only access via the FrameTarget interface.
For now, only instantiate the pacesetter's FrameTargeter.
The reverted Idf9f43b37f3479c94a478d154eaa46f43e0c6c9d had an incorrect
functional change that adjusted `earliestPresentTime` based on the past
VSYNC, which differs from the previous frame's VSYNC when targeting two
VSYNCs ahead. This CL restores the `earliestPresentTime` to be relative
to the previous frame.
