tools/manifestfile.py: Add library for working with manifests.

This splits the manifest file loading logic from makemanifest.py and
updates makemanifest.py to use it.

This will allow non-freezing uses of manifests, such as defining packages
and dependencies in micropython-lib.

Also adds additional methods to the manifest "API":
 - require() - to get a package from micropython-lib.
 - module() - to define a single-file module
 - package() - to define a multi-file package

module() and package() should replace most uses of freeze() and can also
be also used in non-freezing scenarios.
