Follow up on the previous patch :
- Moved the SkStrokeRec class in its own file
- Replaced SkStroke by SkStrokeRec in Ganesh
- Moved path stroking to the Ganesh level in some cases (everytime it isn't required to do it directly in SkGpuDevice). PathEffect and MaskFilter still require path stroking at the SkGpuDevice for now.
- Renamed static functions in SkPath with proper names

* No functionality shold have changed with this patch. This is a step towards enabling Ganesh Path Renderers to decide whether or not to stroke the path rather than always receiving the stroked path as an input argument.

TEST=Try path rendering tests from the gm
