scroggo@google.com ccd7afb6fb Reland 'Add path utils, plus a test for it.'
Build SkPathJoin and SkBasename on windows also.

Previous CL did not build on Windows because the two functions were
accidentally placed inside an ifdef that did not include windows.
Move the functions to the top of the file, and add a comment by the
endif for clarity.
