Move GR_MAKE_BITFIELD_OPS and GrAlignTo to non-GPU files

These have been renamed SK_MAKE_BITFIELD_OPS and SkAlignTo
because nothing seemed particularly GPU/Ganesh specific to them.

I moved the latter to SkTypes.h because we have other align
code there and former to src/SkUtils.h because I didn't know
where else it should go.

The primary motivation was removing the GrTypesPriv.h
include from src/core/SkBlockAllocator.h. I had attempted
some amount of #if SK_SUPPORT_GPU, but that's not as clean
here because both our CPU and GPU backends use the
SkBlockAllocator (as far as I could tell).

This also moves sk_memset* from SkUtils.h to SkOpts.h, because
SkOpts.h requires bringing in RasterPipeline, which seemed
like overkill.
