Rollup merge of #135310 - estebank:issue-135289, r=Nadrieril

Always force non-trimming of path in `unreachable_patterns` lint

Creating a "trimmed DefID path" when no error is being emitted is an ICE (on purpose). If we create a trimmed path for a lint that is then silenced before being emitted causes a known ICE. This side-steps the issue by always using `with_no_trimmed_path!`.

This was verified to fix https://github.com/quinn-rs/quinn/, but couldn't write a repro case for the test suite.

Fix #135289.
