reduce pathops templated code
Pathops uses a template to intersect a pair of curves.
This generates six copies: quad/quad, quad/conic, quad/cubic,
conic/conic, conic/cubic, cubic/cubic.
This CL rewrites the template to generate a single copy,
and leverages a new abstract class, SkTCurve, to dispatch
to one of SkTQuad, SkTConic, or SkTCubic. These classes
are thin wrappers on the existing double curves classes
SkDQuad, SkDConic, and SkDCubic, which do work.
Kevin's BuildStats bot says this saves around 180K on the
release build. Running pathops_unittest shows no significant
performance difference, and the smaller version may be
slightly faster.
