Remove superfluous excludes for Lint cops

What does this MR do and why?

This removes superfluous excludes for the Lint/* cops.

Some Lint cops are disabled, so we’re not touching them, unless the file was deleted.

This contributes to the overall effort in #340515 (closed) and is a prerequisite to merge !88480 (closed) (detecting superfluous/orphaned cop excludes in .rubocop_todo).

A full list of superfluous (and missing file) excludes is in this job log: https://gitlab.com/KevSlashNull/gitlab/-/jobs/2503408370

How to set up and validate locally

1. Run bundle exec rubocop <files> where <files> are the file paths that were removed in this MR.

However, if the pipeline passes, the cop exclusions were indeed superfluous or the excluded files were deleted.
