Add AudioServer.get_driver_name() to get the actual audio driver name

The project setting does not reflect CLI argument overrides
(including `--headless` which sets the audio driver to `Dummy`),
so it can't be reliably used to detect which audio driver is
actually being used at run-time.

Returns the name of the current audio driver. The default usually depends on the operating system, but may be overridden via the [code]--audio-driver[/code] [url=$DOCS_URL/tutorials/editor/command_line_tutorial.html]command line argument[/url]. [code]--headless[/code] also automatically sets the audio driver to [code]Dummy[/code]. See also [member ProjectSettings.audio/driver/driver].

Specifies the audio driver to use. This setting is platform-dependent as each platform supports different audio drivers. If left empty, the default audio driver will be used.
The [code]Dummy[/code] audio driver disables all audio playback and recording, which is useful for non-game applications as it reduces CPU usage. It also prevents the engine from appearing as an application playing audio in the OS' audio mixer.
To query the value that is being used at run-time (which may be overridden by command-line arguments or headless mode), use [method AudioServer.get_driver_name].
