Audio: Select a shared audio device by default (#574)
* Audio: Select a shared audio device by default

This ensures that a non-raw audio device is selected wherever possible.

* Audio: Resolve libsoundio version mismatch between bindings and binaries

It turns out we were using bindings generated with libsoundio 1.1.0 git source, but the binaries we were using were built from master git source. I've rebuilt both binaries and bindings to ensure they are version matched.

This should resolve all outstanding issues with libsoundio (including the Linux segfault issue, and the "cannot open device" Windows issue).

* Audio: Reformat MarshalExtensions

* Resolve code indentation issues

8275bc3c08 Implement libsoundio as an alternative audio backend (#406)
* Audio: Implement libsoundio as an alternative audio backend

libsoundio will be preferred over OpenAL if it is available on the machine. If neither are available, it will fallback to a dummy audio renderer that outputs no sound.

* Audio: Fix SoundIoRingBuffer documentation

* Audio: Unroll and optimize the audio write callback

Copying one sample at a time is slow, this unrolls the most common audio channel layouts and manually copies the bytes between source and destination. This is over 2x faster than calling CopyBlockUnaligned every sample.

* Audio: Optimize the write callback further

This dramatically reduces the audio buffer copy time. When the sample size is one of handled sample sizes the buffer copy operation is almost 10x faster than CopyBlockAligned.

This works by copying full samples at a time, rather than the individual bytes that make up the sample. This allows for 2x or 4x faster copy operations depending on sample size.

* Audio: Fix typo in Stereo write callback

* Audio: Fix Surround (5.1) audio write callback

* Audio: Update Documentation

* Audio: Use built-in Unsafe.SizeOf<T>()

Built-in `SizeOf<T>()` is 10x faster than our `TypeSize<T>` helper. This also helps reduce code surface area.

* Audio: Keep fixed buffer style consistent

* Audio: Address styling nits

* Audio: More style nits

* Audio: Add additional documentation

* Audio: Move libsoundio bindings internal

As per discussion, moving the libsoundio native bindings into Ryujinx.Audio

* Audio: Bump Target Framework back up to .NET Core 2.1

* Audio: Remove voice mixing optimizations.

Leaves Saturation optimizations in place.
