We already have a getGenerationID() method that is Android-only. Can we just
move that out from behind the macro (and it may have a different impl for the
Android build)?

There's the problem that this would be confusing for the reader, since the
functions mean totally different things.

Also the problem that the android builds would use the quite wrong behavior. 

SkPath generation id asserts that "paths with same generation id value have same
amount of modifications". Problematic for example since all rects have same
amount of modifications.

SkPathRef generation id asserts that "paths with same generation id value are
same paths".
