[janderwald] 41352: - Fix a bug in KsTopologyPropertyHandler - Create a KSTOPOLOGY struct when creating the subdevice descriptor and pass the struct to KsTopologyPropertyHandler - Implement enumerating mixer devices - Change handle array to contain the target device type. Mixer handles are not real handles, they are just pseudo handles - Forward KSPROPSETID_Topology request to portcls (sysaudio)

Log:
- Fix a bug in KsTopologyPropertyHandler
- Create a KSTOPOLOGY struct when creating the subdevice descriptor and pass the struct to
KsTopologyPropertyHandler
- Implement enumerating mixer devices
- Change handle array to contain the target device type. Mixer handles are not real
handles, they are just pseudo handles
- Forward KSPROPSETID_Topology request to portcls (sysaudio)
