Closes #111645.
FCP: #111645 (comment)

Note that because const_mut_refs and const_refs_to_cell was stabilized, it's okay to const-stabilize this method as well.

This seems fine to me, but FCP did not include const stabilization so

No objections from the const-eval side.

But yeah the question is whether libs-api wants to retroactively add const to the FCP or start a new FCP.

I am not unilaterally approving a const stabilization on top of the team FCP from #111645. But if there is quorum in the next libs-api meeting or enough 👍 from @rust-lang/libs-api, I think this PR can be merged without a whole new FCP.
