Be more accurate about calculating `display_col` from a `BytePos`

2024-07-18T20:08:38+00:00

No longer track "zero-width" chars in `SourceMap`, read directly from the line when calculating the `display_col` of a `BytePos`. Move `char_width` to `rustc_span` and use it from the emitter. This change allows the following to properly align in terminals (depending on the font, the replaced control codepoints are rendered as 1 or 2 width, on my terminal they are rendered as 1, on VSCode text they are rendered as 2): ``` error: this file contains an unclosed delimiter --> $DIR/issue-68629.rs:5:17 | LL | ␜␟ts␀![{i | -- unclosed delimiter | | | unclosed delimiter LL | ␀␀ fn rݻoa>rݻm | ^ ```
