micropython/mip: Add command-line functionality for the Unix port.

Moves mip.py to mip/__init__.py, so that the optional (added in this
commit) mip/__main__.py can exist to support:

`micropython -m mip install [--target,--index,--no-mpy] package@version`

"install" works by forwarding the arguments directly to mip.install.

Updates mip to v0.2.0 because of the change in directory structure.

This work was funded through GitHub Sponsors.
