libaudiohal@aidl: Provide an example IHalAdapterVendorExtension
This service is necessary for any vendor because all vendor
HAL implementations have some vendor-specific parameters.
An example implementation is added, which is used by Cuttlefish.
Updated the framework client code to handle service crashes
and rebind automatically. This allows to avoid restarting
the audioserver when the parameter parser service crashes.
Bug: 321651892
Test: atest audiorouting_tests
