Custom proc macro for test functions no longer provide "Run Test" codelens

This regression has been there for quite some time, but I decided to report it only today, sorry...
I remember that at some point this worked and rust-analyzer showed codelens on top of a proc macro attribute that contains test in its signature.

E.g. the following code showed this codelens:

just like it shows it when I switch the proc macro to tokio::test

I even remember reviewing a PR that initially added a heuristic that searches for a substring "test" in the proc macro name to gate the addition of that codelens, but that was a long time ago and I assume this heuristic either gone broken or was changed [un]intentionally.

I suggest we fix this and return that codelens back.

No source file or test is named. Reproduce the custom proc-macro and tokio::test examples, then trace rust-analyzer's Run Test codelens handling for proc-macro attributes; done means the custom attribute receives the codelens again and the regression is covered.
