Remove char::to_titlecase. Fix #26555

Browse Source 
I added it because it was easy (same a `char::to_lowercase`,
just a different table), but it doesn’t make sense to have this
in std but not str::to_titlecase, which would require
https://github.com/unicode-rs/unicode-segmentation

At some point in the future this feature will be available
(both on char and str) in a crates.io crate.
