This adds a new MODE_PYPROJECT, which gives basic support to allow
packaging a small subset of micropython-lib packages to PyPI.
This change allows a package in micropython-lib to:
- Add a "pypi" name to its metadata indicating that it's based on a PyPI
package.
- Add "stdlib" to its metadata indicating that it's a micropython version
of a stdlib package.
- Add a "pypi_publish" name to its metadata to indicate that it can be
published to PyPI (this can be different to the package name, e.g. "foo"
might want to be published as "micropython-foo").
When a package requires() another one, if it's in MODE_PYPROJECT then if
the package is from pypi then it will record that as a pypi dependency
instead (or no dependency at all if it's from stdlib).
Also allows require() to explicitly specify the pypi name.
