signature: Fix and simplify for mypy compatibility

There was a problem with the typing module for Python2
that showed the wrong name.

The generated signature files are further simplified.
They no longer contain fancy definitions like "Char", which
made little sense and was replaced by "int", which our
competitor does as well.

The mypy compatibility should be considered mostly complete.
Update.. QChar was not changed to "int" but "str" because we
got clashes. Therefore, recreation of the registry was necessary.

Hard to solve stay the definitions
    "Virtual, Missing, Invalid, Default, Instance".
They are very rarely used for special cases. Mypy cannot
see these definitions since the module path does not exist
in the file system.

I tried hard to fix this by building a mypy plugin, but I seem to
be forced to generate real files in a temp dir. This was too much
effort. A plugin may make sense in the future when we need to
improve the type support.
