feat(bluetooth): Add back profiles, split fixes.

* Add back in profiles, not using Zephyr
  BT identity infrastructure.
* Restore additional `&bt` commands for profile
  operations.
* Fix for split pairing and subscriptions, since
  Zephyr persists subscriptions across connects.
* Remove keymap from peripheral builds, reduces
  firmware size, and avoids unneeded attempts
  to send HID data.
