drm/amd/display: Forward periodic ABM keep-alive scenario to DMU
[Why & How]
1. The periodic ABM full-frame update for VESA PR is now owned
by the DMU timer.
2. In PR_update_state, compute whether the current scenario allows
the periodic keep-alive (not CTS, not front-buffer rendering,
not force-full-frame, content actively updating) and forward it
via the abm_periodic_ffu_allowed runtime flag only when it changes.
