[SF] Updates to not send hints without a present being followed
Updates the hint to be sent through a frame scheduling.
Reduce the number of callbacks to notifyExpectedPresentIfRequired
by making calls only through EventThread.
Timeout hint is sent directly without scheduling a frame
to avoid delay in sending the hint.
A hint through setTransactionState for ScheduleOnTx will
be in a follow up CL
