LeAudio: Make device inactive if Media is not available

When remote device makes MEDIA context unavailable, Bluetooth stack will
not allow to create the Le Audio stream to the device.

Since Audio Framework cannot yet choose audio device based on the
context type, whenever Bluetooth detects that Audio Framework tries to
open multiple times a stream which context is not allowed on the remote
side, the LeAudio device will become inactive and stream will be
redirected to another active audio device.

When MEDIA context will become available again for this device, the LeAudio headset will
be set as active device again.

Note, that if while Media context is unavailable for Device A, and another LeAudio
devive (Device B) will become active,  the Device A will not becaume
Active when Media context type will become available again.

Note: Feature is available only when flag is set:

$> adb shell setprop persist.device_config.aconfig_flags.bluetooth.com.\
android.bluetooth.flags.leaudio_enable_health_based_actions true
