audio policy: fix LE audio input device selection.

Do not select LE Audio input device by default when available
for any capture use case: starting capture over LE audio will
disturb any active playback so it is better that applications
explicitly select the LE audio input device with
AudioRouting.setPreferredDevice() API.
For voice communication use case and calls, the LE audio input
device will still be selected via AudioManager.setCommunicationDevice()
API.
