Simplify Python Imports For Embedding

After the project split, shiboken exposed its own modules, and the
overall structure with shiboken2.support.signature and
PySide2.support.signature was already quite complicated.

When introducing embedding, it is necessary to have some support
folder that gets unpacked from a zipfile. That means, the shiboken2
root directory would be in the zip file in the embedding case.

This does not only increase the complexity, it further means
that we must make shiboken2.so available in the shiboken2
containing zipfile!

In order to avoid that, we stop the dependency from the two
support directories and use shibokensupport, instead. The
simplification of the loader and other modules is also significant.
