pip_install_wheel: install wheel with a glob

Now that the build systems that use pip_install_wheel are all building
their wheel into a directory that we knew was empty before, we can just
install *.whl and not need to know the precise names.

By design a pyproject.toml will always build a single wheel, so there
shouldn't be any way for this to end up installing more than expected.

This obsoletes PIP_INSTALL_PACKAGE and PYPA_WHEEL, neither of which are
needed anymore.
