Subject: Reduce verbosity of some type ascription errors

* Deduplicate type ascription LHS errors
* Remove duplicated `:` -> `::` suggestion from parse error
* Tweak wording to be more accurate
* Modify `current_type_ascription` to reduce span wrangling
* remove now unnecessary match arm
* Add run-rustfix to appropriate tests
