SDL 3.0 data definitions

These are some SDL 3.0 structures and data definitions used on the GDK.
We just compile them here for a quick reference but also, the link to the SDL 3.0 wiki is provided.

"#" (ISO USB keyboards actually use this code instead of 49 for the same key, but all OSes I've seen treat the two codes identically. So, as an implementor, unless your keyboard generates both of those codes and your OS treats them differently, you should generate SDL_SCANCODE_BACKSLASH instead of this code. As a user, you should not rely on this code because SDL will never generate it with most (all?) keyboards.)
