Rollup merge of #127660 - tgross35:const_strlen-rename, r=dtolnay 

Rename the internal `const_strlen` to just `strlen`

Since the libs and lang teams completed an FCP to allow for const `strlen` ([1]), currently implemented with `const_eval_select`, there is no longer any reason to avoid this specific function or use it only in const.

Rename it to reflect this status change.
