drm/amdkfd: set CP_IQ_WAIT_TIME2.QUE_SLEEP on GFX 12.1

Browse source

The optimized QUE_SLEEP was only programmed on the HWS packet-manager
path via a PM4 WRITE_DATA packet, which is skipped when MES is enabled.

Add gfx12.1 get_iq_wait_times/build_dequeue_wait_counts_packet_info
callbacks and program CP_IQ_WAIT_TIME2 through the MES WRITE_REG op at
start_cpsch, per XCC.
