Jonathan Brouwer 2834b1654a Rollup merge of #155068 - lapla-cogito:multibyte_char, r=mati865 ...

Fix ICE in `span_extend_prev_while` with multibyte characters

Fixes https://github.com/rust-lang/rust/issues/155037

The function assumed that the character found by `rfind` was always one byte wide, using a hardcoded `1` instead of `c.len_utf8()`. When a multibyte character appeared immediately before the span, this caused the resulting span to point into the middle of a UTF-8 sequence, triggering an assertion failure in `bytepos_to_file_charpos`.
