[2/2] settings: expandable volume panel and tweaks

Setting to disable volume adjust sounds (VOLUME_ADJUST_SOUNDS_ENABLED)
This is so annoying :)

Enhanced dialog to add checkbox for unlinking ringer and
notification volume (VOLUME_LINK_NOTIFICATION)

EDIT:
No idea why google changed the order
Media is now above ringer but in volume panel
its different. So which one to change? :)

Move volume adjust sound option to more native place (2/2).

Our new UX concept includes saving more settings headers possible.
Move this into Volumes settings fragment. Also update description string.

PS2: Update description string.
