Update additional tools to take a GrDirectContext

GM was updated in:
https://skia-review.googlesource.com/c/skia/+/300172 (Make GM::onGpuSetup take a GrDirectContext)

This CL updates: skpbench, nanobench, and some testing infrastructure.

Only minor changes were made to the unit tests as they will be updated
en masse in a follow up cl.
