SCUMM/FM-TOWNS: start rewriting audio code

- Start rewriting audio code for FM-TOWNS versions of Loom, Indy3 and Monkey Island 1 using the recently added code in towns_audio.cpp (Zak should work the same way, but I can't test, since I don't own that one).
- All sound types (pcm, euphony and cd audio) now support volume and balance control (e.g. try walking into/out of the kitchen and opening/closing the door in the Scumm Bar in Monkey Island 1 or walking into/out of the circus tent).
- Pcm sounds now support proper loop start/end and note offsets (e.g. try out the hammer sound in the forge in LOOM for example).
- some other minor improvements
- The FM-Towns versions of Indy 4 and Monkey Island 2 are not affected. I don't have Monkey Island 2, but I presume that it will work like Indy 4. Adding support for these will be a separate task, since they work quite differently.
