Fix issue where GrQuadPerEdgeAA GP doesn't emit coord transforms

This happens when all the FPs are sampled with explicit coords.

The GrGLSLGeometryProcessor::emitTransforms() helper required a valid VS
var for local coords even when all FPs use explicit coords and wouldn't
use a local coords var. It now only requires the variable be valid if
there is an FP with a coord transform that is not explicitly sampled.
