audio: Parametrize core VTS tests
Parametrize tests to accept IDevicesFactory instance name
and IDevice instance name. For audio HAL versions 2..5
the factory instance name is taken from the VTS environment,
and the device is always "primary". For the next versions
the factories are discovered by the test, and the devices
are taken from the audio policy configuration
(to be implemented, see added FIXME comments).
Split the Environment class into two versions: for HAL 2..5
and for next versions. They use different base class.
Move device factories and device caching into dedicated
classes DevicesFactoryManager and DeviceManager. They deal
with instance caching and proper release of server resources.
