tools/sort_sources.py: sort C++ source file names in build files.

tools/git/move_source_file.py updates C++ source file names in
build files for you, but it does not sort the updated file names.

With this tool, you can sort C++ source file names in build files
(both GYP and GN files supported) automatically. It's not perfect
but should work reasonably well.

BUG=456014
TEST=Run the tool against some build files. The results are included in the patch.
