re-run tools/rewrite_includes.py

PS2 adds a rewrite for Skia #include <...> to #include "...", letting
them be otherwise rewritten and sorted too.  (We do need one exception
for the Vulkan headers, which will otherwise be rewritten to always
point to our own.)  I don't think it's particularly important to
favor "" or <>, but picking one keeps things consistent.

PS3 adds a missing SkMutex.h include.

PS4 fixes a terrible readability problem.
