Prepare for split sample chip instrument

Browse source 
(MSM6258, MSM6295, QSound, Sega PCM, ADPCM-A, ADPCM-B, YMZ280B, RF5C68)
Instrument color and icons are placeholder.

different volume range, hard panned/soft panned and/or independent volume per output, chip-dependent features (global volume, echo, etc)
Allow use sample in instrument tab for chip with sample support
Prepare to support X1-010 Seta 2 style bankswitch behavior
Prepare to support AY89x0 PCM DAC
Support volume for PCE sample (DAC)
Fix Lynx, Y8950 sample pitch matches to sample preview
Support PCM DAC with backward and pingpong loop mode
Reduce some codes
Add Sega PCM, AY89x0, QSound, PCM DAC, Lynx per-channel debug support
