[SF] Move the notifyExpectedPresentHint call to SF

This moves the notifyExpectedPresent call off the HWComposer,
HWComposer should only be access with mStateLock or from the main
thread, and moving this to SF achieves that.

Schedule the HWComposer::notifyExpectedPresent
call on the main thread once the decision to
send the hint is made
