anything needed before both this and #76156 can be stabilized?

@programmerjake I think there is no blocker for stabilization since the functions just return a field value.
However, I'm not sure if Location::caller can be stabilized. Additional testing is probably needed regarding its use in const generic parameters, macros, and so on.

@programmerjake @lilasta doesn't seem to be any blockers here and this has sat long enough so all what's missing is someone sending the pr to stabilise it, so feel free to do so if you are interested
