This PR makes `#guard_msgs` to treat `trace` messages separate from `info`, `warning` and `error`. It also introduce the ability to say `#guard_msgs (pass info`, like `(drop info)` so far, and also adds `(check info)` as the explicit form of `(info)`, for completeness. Fixes #8266

numerals are polymorphic in Lean, but the numeral `22` cannot be used in a context where the expected type is
|
||
α
|

due to the absence of the instance above
