Reland "Add driver bug workarounds to GrCaps"

This is a reland of 328490c6a1625ce51d0e81688e0c85c79c400d86

Original change's description:
> Add driver bug workarounds to GrCaps
> 
> This moves GrDriverBugWorkarounds to include so that it can be included
> by GrCaps.  This also makes GrContextOptions a nearly empty class in
> the case of !SK_SUPPORT_GPU so that non-gpu builds don't need to build
> in GrDriverBugWorkarounds.cpp.
