Rollup merge of #99140 - TaKO8Ki:implement-is-accessible-span, r=fee1-dead
Implement `SourceMap::is_span_accessible` This patch adds `SourceMap::is_span_accessible` and replaces `span_to_snippet(span).is_ok()` and `span_to_snippet(span).is_err()` with it. This removes a `&str` to `String` conversion.
