Way to declare intrinsics in code

[MarcellPerger1]

We should declare intrinsics in ST code and then have imports or pseudo-imports (includes?) to add those to all files.

Maybe like:

def glideToXY(number secs, number x, number y) @native("motion_glidesecstoxy", secs, x, y) {}

Though this requires an import system (far away in future)
