Rollup merge of rust-lang#134043 - ehuss:unicode-version, r=jieyouxu

Add test to check unicode identifier version

This adds a test to verify which version of Unicode is used for identifiers. This is part of the language, documented at https://doc.rust-lang.org/nightly/reference/identifiers.html#r-ident.unicode. The version here often changes implicitly due to dependency updates pulling in new versions, and thus we often don't notice it has changed leaving the documentation out of date. The intent here is to have a canary to give us a notification when it changes so that we can update the documentation.
