Use a qualified path for grit/content_resources.h.

The source file changes were done using:

  for f in $(git grep -l '"grit/content_resources.h"' -- '*.cc' '*.mm'); do
    sed -i -e 's/"grit\/content_resources.h"/"content\/grit\/content_resources.h"/' $f ;
  done
  tools/git/for-all-touched-files.py -c "tools/sort-headers.py -f [[FILENAME]]"

The gyp, gn, and DEPS changes were lovingly hand-crafted.
