fix macros `@which`, `@edit`, `@functionloc`, `@less` for `literal_pow` case. (#53713)
The macros `@which`, `@edit`, `@functionloc`, `@less` from `InteractiveUtils`, if
applied to the case of literal powers, like `a^12` or `2^-1` used to direct the
user to function `^`, while the compiler generates code for `Base.literal_pow`.
Now the user is shown the code the compiler generates.
