Rollup merge of #130713 - bjoernager:const-char-make-ascii, r=Noratrieb

Browse Source 
Mark `u8::make_ascii_uppercase` and `u8::make_ascii_lowercase` as const.

Relevant tracking issue: #130698

This PR extends #130697 by also marking the `make_ascii_uppercase` and `make_ascii_lowercase` methods in `u8` as const.

The `const_char_make_ascii` feature gate is additionally renamed to `const_make_ascii`.
