[Ryujinx.Audio.Backends.SDL2] Address dotnet-format issues (#5364)

* dotnet format style --severity info

Some changes were manually reverted.

* dotnet format analyzers --serverity info

Some changes have been minimally adapted.

* Address dotnet format CA1816 warnings

* Address most dotnet format whitespace warnings

* Run dotnet format style after rebase

* Run dotnet format analyzers after rebase

* Simplify properties and array initialization, Use const when possible, Remove trailing commas

* Revert "Simplify properties and array initialization, Use const when possible, Remove trailing commas"

This reverts commit 9462e4136c0a2100dc28b20cf9542e06790aa67e.

* dotnet format whitespace after rebase

* Update src/Ryujinx.Audio.Backends.SDL2/SDL2HardwareDeviceDriver.cs
