Restore Path cheap copying (refcount/COW PathStream)

Summary Restore Path cheap copying (refcount/COW PathStream)

After 265569@main, copying a Path with a PathStream impl results in cloning the PathStream, which might be large. This breaks the assumption of most of the existing code, that copying a Path is cheap because it's just refCounting a CGPathRef. So we should restore cheap copy, and make the PathStream copy-on-write.
