Unify reference to BluetoothProfiles.STATE_foo

STATE_{DIS,}CONNECT{ED,ING} are use widely in java, there is only one
definition in BluetoothProfile.
This change unify all the reference with static import and allow for the
code to be a bit lighter

sed regex runs are:
's/(BluetoothProfile\.STATE/(STATE/'
's/{BluetoothProfile\.STATE/{STATE/'
's/ BluetoothProfile\.STATE/ STATE/'
