PyAPI: Support for 'None' string args from Python
This is needed because some RNA functions differentiate a NULL 'char *'
argument from an empty string.
Previously a NULL argument could be passed when the C definition
defined the default as NULL and the argument wasn't passed
which is a fairly hidden way of handling things.
Now strings use `PROP_NEVER_NULL` by default
which can be cleared for function arguments that allow None -> NULL.
