Send syncStatus and return FrameCommitCallback in FrameCallback
FrameCallback sends back the syncStatus and allows the caller to return a FrameCommitCallback. This is so the caller can evaluate the results of the sync and determine if it wants to continue waiting for a commit callback. In cases, where the sync has failed, there will never be a commit callback so the caller can avoid waiting. This is partically helpful for VRI because it wants to sync with a frame that will draw, but also doesn't want to get stuck indefinitely waiting on the callback. VRI can check the syncStatus and only handle blast sync and/or reportDraw when its determined that a draw will happen. This allows VRI to remove frameCompleteCallback since it can now wait until a buffer has drawn instead of when the vsync has completed. This makes sure it waits on FrameDropped since that result indicates HWUI will draw on the next vsync Test: BlastSync Bug: 200284684 Change-Id: Ic6e2f08ea21ac8a1634a3389c927fcb68ede3f7b
