Jonathan Brouwer 6bf2ce0f38 Rollup merge of #154849 - Jules-Bertholet:case-ignorable, r=Mark-Simulacrum ...

Promote `char::is_case_ignorable` from perma-unstable to unstable

(Take two of https://github.com/rust-lang/rust/pull/154658, which was closed when GitHub Codespaces somehow managed to squash the entire commit history of rust-lang/rust into one commit)

This function is currently used in the implementation of `str::to_lowercase()`. There is no reason to restrict it to the stdlib, though. Reimplementations of string casing for types other than `str` -> `String` shouldn't need to waste space with a duplicate copy of this table.
