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. Previously reviewed at https://codereview.chromium.org/15747004/ Review URL: https://codereview.chromium.org/15740024 git-svn-id: http://skia.googlecode.com/svn/trunk@9295 2bbb7eff-a529-9590-31e7-b0007b416f81
