Add rules for accessing the related bluetooth_audio_hal_prop
This change allows those daemons of the audio and Bluetooth which
include HALs to access the bluetooth_audio_hal_prop. This property is
used to force disable the new BluetoothAudio HAL.
- persist.bluetooth.bluetooth_audio_hal.disabled
Bug: 128825244
