gdbus-codegen: Move from optparse to argparse

Browse Source 
The optparse module is deprecated since version 2.7 and the
development continues with the argparse.

The code has been moved from optparse to argparse when parsing
command-line options. This has also led to the deprecation of the
`--xml-files`, and positional arguments should be used instead.
