tools/makemanifest.py: Merge make-frozen.py. 

Takes the functionality from tools/make-frozen.py, adds support for
multiple frozen directories, and moves it to tools/makemanifest.py.

#!/usr/bin/env python
#
# Create frozen modules structure for MicroPython.
#
# Usage:
#
# Have a directory with modules to be frozen (only modules, not packages
# supported so far):
#
# frozen/foo.py
# frozen/bar.py
#
# Run script, passing path to the directory above:
#
# ./make-frozen.py frozen > frozen.c
#
# Include frozen.c in your build, having defined MICROPY_MODULE_FROZEN_STR in
# config.
