Track quad type on GrQuad directly

This makes subsequent higher-level drawing APIs more compact, and
shouldn't come with a performance hit. Everywhere we used to need
a GrPerspQuad, we'd also take the GrQuadType as a second argument.
The quad list types already deconstruct the quad so there's no
extra overhead in the op's memory usage.

It also improves usability and decreases the likelihood that an
incorrect quad type is ever associated with the quad.
