Mike Klein c0bd9f9fe5 rewrite includes to not need so much -Ifoo
Current strategy: everything from the top

Things to look at first are the manual changes:

   - added tools/rewrite_includes.py
   - removed -Idirectives from BUILD.gn
   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

No-Presubmit: true

* This is a simple utility designed to extract the paths from an SKP file and then isolate a single
* one of them via bisect. Use the 'x' and 'X' keys to guide a binary search:
*
* 'x': Throw out half the paths.
* 'X': Toggle which half gets tossed and which half is kept.
* 'Z': Back up one level.
* 'D': Dump the path.
