Rollup merge of #89258 - est31:const_char_convert, r=oli-obk
Make char conversion functions unstably const

The char conversion functions like `char::from_u32` do trivial computations and can easily be converted into const fns. Only smaller tricks are needed to avoid non-const standard library functions like `Result::ok` or `bool::then_some`.
