SF: Move present timing to FrameTargeter
Split out from I2c27dc709afd1f33bddbf9c2ca1cd61dd335f66c.
Store earliestPresentTime on the FrameTarget, like expectedPresentTime,
so it can be stored per display.
Add FrameTargeter::computeEarliestPresentTime. This calculation was
previously done in SurfaceFlinger, using data mostly contained in the
FrameTargeter. This will simplify computing this per display.
Move computation of the earliestPresentTime to
FrameTargeter::beginFrame. Add a scheduler::Feature to track whether
ExpectedPresentTime is supported.
Make previousFrameVsyncTime and wouldPresentEarly protected, now that
they are only called by FrameTargeter (subclass) and tests.
Make the test a friend of FrameTarget for accessing the above methods.
