Robert Phillips 0c43db950c [graphite] Make GrBlend shareable between Graphite and Ganesh
Additionally make the enums enum-classes.

We will need this to specify fixed function blend modes in Graphite.

This CL is mainly mechanical (i.e., global replace) but some fix-ups were required for our internal bit twiddling with the enum-classes.
