BluetoothAudio HAL: flip to be enabled by default
Change to new properties + swap audio XML files, and supports following
scenarios:
1) (default) audio_policy_configuration.xml
Using BluetoothAudio HAL (+ A2DP offload if supported)
2) audio_policy_configuration_a2dp_offload_disabled.xml
Using BluetoothAudio HAL only when A2DP offload is supported but
disabled.
3) audio_policy_configuration_bluetooth_legacy_hal.xml
No BluetoothAudio HAL nor A2DP offload
Bug: 126304229
Test: Switch BluetoothAudio HAL and A2DP offload manully

+ This contains both permanently attached devices and removable devices.
+ “mixPorts”: listing all output and input streams exposed by the audio HAL
+ “routes”: list of possible connections between input and output devices or between stream and
+ devices.
+ "route": is defined by an attribute:
+ -"type": <mux|mix> means all sources are mutual exclusive (mux) or can be mixed (mix)
+ -"sink": the sink involved in this route
+ -"sources": all the sources than can be connected to the sink via vis route
+ “attachedDevices”: permanently attached devices.
+ The attachedDevices section is a list of devices names. The names correspond to device names
