This allows argument and return position impl Trait in the signature of a const fn. It also allows impl Trait in other const-contexts, although this is only possible with additional feature gates (see #63065).

Formerly, this was gated under #![feature(const_fn)].

    This was stabilized last month in #93827 and will likely be in the next release, 1.61.
