[AUDIO] Implement volume control support (#6922)

Implement volume level changing for Aux/MidiOut/WaveOut devices. It's represented the following WINMM functions:
- auxGetVolume,
- auxSetVolume,
- midiOutGetVolume,
- midiOutSetVolume,
- waveOutGetVolume,
- waveOutSetVolume,
which are calling the followind messages appropriately:
- AUXDM_GETVOLUME,
- AUXDM_SETVOLUME,
- MODM_GETVOLUME,
- MODM_SETVOLUME,
- WODM_GETVOLUME,
- WODM_SETVOLUME.
This fixes volume control for several 3rd-party programs (like Fox Audio Player 0.10.2 from Rapps, Winamp 2.95 with WaveOut plugin). However it does not fix changing the volume in system volume mixers (SndVol32, MMSys), since they are using their own functionality instead. They technically do the same things, but apart from the functions mentioned above.
