Kevin Lubick cbc954bf57 [includes] Remove include link between SkPath.h and SkPathRef.h 
According to go/chrome-includes [1], this will save about
185MB (0.08%) off the Chrome build (some of which is handled
by https://skia-review.googlesource.com/c/skia/+/512776).
http://screen/3foDapQ5BN7srcG

This adds several forward declares and moves several
implementations from SkPath.h to SkPath.cpp.

This also removes privateSetConvexity from SkPathBuilder
because the SkPathConvexity being set to a non-zero default
value would have required moving the enum out of SkPathRef
or adding an include link. This private API was only used
in one location, so I just opted to remove it.
