SurfaceFlinger: get nextPredictedPresentTime directly from frame timeline
ag/13715677 moved the call to check whether a frame is early or not
before a transaction is applied.
This created a bug in BufferStateLayer::nextPredictedPresentTime since
it is checking the drawing state surface frame, which is not valid since
the transaction is not applied yet. This CL is fixing this by pasing the
vsync id itself, and getting the expected present time base on that
vsync id.

Test: launch an app and observe systraces
