feat(endpoints): update on BLE profile change

Browse Source 
Added zmk_ble_active_profile_is_connected() to allow code outside ble.c to check
the status of the active profile, and changed the ble_active_profile_changed
event to also notify when the active profile connects or disconnects.

Changed endpoint selection to to also update when the active profile changes,
connects, or disconnects.
