Add Nintendo Switch Pro controller prompts

[LottAustin]

Feature description

So, the SDL settings for the NS Pro controller face buttons don't map to the same layout as an Xbox or Playstation controller in Fullscreen mode. The option to swap the confirm button isn't really sufficient to fix this since navigation doesn't change and the prompts available are still incorrect.

There are a couple of ways this I see that this could be addressed:

1. add a new button prompt layout for Switch controllers (lowest effort)
2. Allow user button remapping and add a generic prompt layout (similar to Steams universal face button layout)

I did see some close issues that where possibly related to this but the issue didn't really seem to be resolved in any case.
