Enable draw-based pipeline prewarming before Graphite's precompilation

As with Ganesh, the draws will block SF, but then the additional
pipelines covered by Graphite's precompilation will be compiled
asynchronously.

This change is intended as a temporary stopgap to de-risk missed
pipeline jank from cases that aren't yet added to Graphite's
precompilation.
