Add support for semaphores to be inserted on GrContext flush

This also moves the logic of inserting semaphores down into GrDrawingManager
and finishFlush on GrGpu. With it being on finishFlush, there should be no
issues when the DrawingManager starts respecting the proxy passed in assuming
it always calls finishFlush at the end (which it should).
