Detect id device is touch enabled

Hi. Is there a way to detect if a device is touch enabled?

It looks like theres a way:

https://wiki.libsdl.org/SDL_GetNumTouchDevices

But this is not implemented

Currently, you would have to listen for the first event, or do it conditionally per platform (iOS, for example, can be presumed to have touch)

I will do it conditionally per plataform. Thanks.
