Jasmine Cha 0a614e1716 audio: update playback tuning and volume curve ...

Merge notes:
* Update full volume curve for sound quality (bass, depth, stereo)
* Updated max volume for louder, punchier, more powerful experience
* Updated volume curve to pass power budgets (based on volume
  20-25 = P10 + 300mW and volume 1-19 = P10).
  - Power testing only based on speaker load (not full monsoon battery
    testing).
  - Only risk at volume 22, over power budget by ~50mW, very small
    increase but can deal with it next iteration before dogfood.
* Update volume curve top volumes to pass heat budget at 41-42C skin
  temp for nominal use case (13dB CF pink noise).

Tuning gaps:
* No thermal throttle merged (2nd LL) yet (next iteration pre dogfood),
  so TMO use case unknown still.
* No BAACL tuning merged yet (next iteration pre dogfood)
* Still some bass distortion at top volume steps (need to address bass
  and piano distortion still).  Not clean but very natural vocals w/
  decent pitch reproduction.
