Rollup merge of #132544 - dianne:unstable-library-feature-backticks, r=compiler-errors

Browse source 
Use backticks instead of single quotes for library feature names in diagnostics

This PR changes the text of library feature errors for using unstable or body-unstable items. Displaying library feature names in backticks is consistent with other diagnostics (e.g. those from `rustc_passes`) and with the `reason`s on unstable attributes in the library. Additionally, this simplifies diagnostics when supporting multiple unstable attributes on items (see #131824) since `DiagSymbolList` also displays symbols using backticks.
