RenderEngine, SF: gate HDR priming behind property

This should make it so that devices which do not see any benefit from
priming those shaders can avoid computing them at boot time.

Bug: b/295257834
Test: manual - delta of -37 shaders generated before/after this patch
Test: atest librenderengine_test
