Revert "Add support for semaphores to be inserted on GrContext flush"

This reverts commit cd1416efbc7af6f115dbaa09dce48e075d1d96ca.

Reason for revert: speculative, to try to fix roll see gpu_tests.pixel_integration_test.PixelIntegrationTest.Pixel_GpuRasterization_ConcavePaths

Original change's description:
> 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).
