render3d: to its floor - messages in declared helpers, post and DLSS set up at start, lists sized

Browse source 
Seventeen inline messages (allocation failures, missing conversions, the no-pipeline and compressed-
target warnings, resize and swapchain lines, the test-frame camera line, DLSS evaluate, shadow memory,
stream and terrain debug, the water test) are each a function of their own under @alloc_ok, taking
numbers, so the paths that say them hold no site. post_measure's two 1x1 exposure targets are made in
post_init and DLSS's evaluate structs in gsl_init; DLSS's camera up is a state field. The lists play
pushes into (retired, free ranges, spare ids, the per-buffer gpu flags, the stage and the actor spares)
get their room at start-up (gvk_room_*, actor_room), so a push fits. Compiled (steady).
