Ross Burton 4f22a746d8 classes/python_pep517: implement a standard do_compile
As all PEP517-compliant build systems have a universal API, we can ask
that users of this class set PEP517_BUILD_API to the class that implements
this API and call it ourselves, instead of users needing to implement
near-identical do_compile tasks themselves.
