libcamera: bound_method: Move sequence and generator to BoundMethodBase

The sequence and generator member types of BoundMethodArgs are not
dependent on the template arguments of BoundMethodArgs. To prepare for
template specialization of BoundMethodArgs and avoid code duplication,
move them to the BoundMethodBase class.
