Creates a default save data for the application given a user ID.

These functions are not stubbed and are called fairly often. Due to the nature of how often they're called, we should keep them marked as LOG_TRACE instead of LOG_DEBUG or LOG_WARNING

Avoids the use of global accessors, removing the reliance on global
state. This also makes dependencies explicit in the interface, as
opposed to being hidden

We can remove this since its already a f32 value

Volume is a f32 value. (SwIPC describes it as a u32, but it is actually f32 as corroborated by switchbrew docs and SetAudioDeviceOutputVolume)

 ```cpp
const f32 volume = rp.Pop<f32>();
```

This commit ensures that all backing memory allocated for the Guest CPU
is aligned to 256 bytes. This due to how gpu memory works and the heavy
constraints it has in the alignment of physical memory.

Audio devices use the supplied revision information in order to
determine if USB audio output is able to be supported. In this case, we
can only really handle using this revision information in
ListAudioDeviceName(), where it checks if USB audio output is supported
before supplying it as a device name.

A few other scenarios exist where the revision info is checked, such as:

- Early exiting from SetAudioDeviceOutputVolume if USB audio is
  attempted to be set when that device is unsupported.

- Early exiting and returning 0.0f in GetAudioDeviceOutputVolume when
  USB output volume is queried and it's an unsupported device.

- Falling back to AHUB headphones in GetActiveAudioDeviceName when the
  device type is USB output, but is unsupported based off the revision
  info.

In order for these changes to also be implemented, a few other changes
to the interface need to be made.

Given we now properly handle everything about ListAudioDeviceName(), we
no longer need to describe it as a stubbed function.

The revision querying facilities are used by more than just audren. e.g.
audio devices can use this to test whether or not USB audio output is
supported.

This will be used within the following change.

Trims out the lingering reliance on global state out of the audio code.

This service function only ever returns a result and nothing more.

AudioDevice and AudioInterface aren't valid device names on the Switch.
We should also be returning consistent names in
GetActiveAudioDeviceName().

While we're at it, we can also handle proper name output in
ListAudioDeviceName, by returning all the available devices on the
Switch.
