Enable the packed_resources target on Windows.

Enable the packed_resources target on Windows.

This target generates the locale .pak files on Windows.  Since nothing
depends on this target, it doesn't build by default (they're not used
yet).

Specific changes:
- Have locale_settings_win.grd generate .pak files.
- Use pymod_do_main to avoid some shell escaping problems (and it's a bit
  faster).
- Rewrite repack_locales.py to work with pymod_do_main.

I'm always unsure about the difference between < and > (one is "early variable",
one is "late variable", but I don't know why this is important) – why was this

I don't understand the difference either.  I was just copying from
build/grit_action.gypi.
