Introduce a new DISTUTILS_USE_PEP517 value "no" that stands for
"no build system". This is primarily meant to replace the legacy
distutils-r1 logic used for bootstrapping baseline PEP 517 packages.
At the same time, it provides a convenient replacement for some
of the uses of python-r1.
In this mode, the eclass does not add PEP517-specific dependencies
and does not export default python_compile() and python_install()
implementations. However, it does set dependencies, REQUIRED_USE
and enables sub-phase usage (with respect to DISTUTILS_OPTIONAL).
It also permits using distutils_enable_{sphinx,tests}.
