Dynres: hold through a savestate load, no fast descent

Browse Source 
A load's first frames re-stage VRAM, the HD cache and pacing; treating
them as a heavy scene dropped 18x -> 11x within a second of every load
and the level climbed back slowly. Hold for the whole 2 s request and do
not arm fast descent on a load.
