Use DrawQuad struct to group device+local coords

This is part of a series to make it easier to manipulate the device and
local coordinates as the ops are being created. By instantiating a
single DrawQuad and allowing the functions to avoid having to copy the
GrQuads before making modifications (e.g. cropping, normalization,
or perspective clipping).
