Provide a helper class to use pip to install wheels built by either
bdist_wheel or a PEP-517 backend.
Set pip install arguments via PIP_INSTALL_ARGS, which can be overriden
by recipes.
Pass --root and --prefix to ensure that pip installs things into the
proper place in sysroot.
By passing --no-deps and --no-index we avoid finicky dependency
checking (pip expects wheels in its cache) and avoid trying to fetch
wheels from pypi.org. This is basically the same behavior we have now,
the dependencies should be declared in the recipe.
pip install changes the python interpreter in scripts installed in
${bindir}, e.g. to #!/usr/bin/nativepython3, correct the behavior after
install to #!/usr/bin/env python3.
