[Feature Request] Add force_audio_output setting to Rosalina Menu

[AmbrosiaEgg]

While the hardware issue I experience likely isn't common, I have an issue where my N3DSXL's headphone port is stuck thinking something is plugged into it even when there isn't. The recent addition of the force_audio_output = speakers option has finally allowed me to use my3DS without headphones again, but being able to change this setting more easily would be very much appreciated. If it were added to the Rosalina Menu, the hardware issue, uncommon as it may be would be reduced to a minor annoyance.

Whoops saw the old compilation thread for Rosalina feature suggestions, thought to move this suggestion there, and then realized that compilation thread is closed.
