[AMDGPU][SIInsertWaitcnts] Track SCC. Insert KM_CNT waits for SCC writes. (#157843)
Add new event SCC_WRITE for s_barrier_signal_isfirst and s_barrier_leave,
instructions that write to SCC, counter is KM_CNT.
Also start tracking SCC for reads and writes.
s_barrier_wait on the same barrier guarantees that the SCC write from
s_barrier_signal_isfirst has landed, no need to insert s_wait_kmcnt.
