remove `Ty::is_copy_modulo_regions`

Using these functions is likely incorrect if an `InferCtxt` is available, I moved this function to `TyCtxt` (and added it to `LateContext`) and added a note to the documentation that one should prefer `Infer::type_is_copy_modulo_regions` instead.

I didn't yet move `is_sized` and `is_freeze`, though I think we should move these as well.

r? `@compiler-errors` cc #132279
