Bump ruff version and remove pylint from the linter list. Fix any new

Ruff covers many of the pylint rules. Since pylint is not enabled in
this repo and runs slow, we remove it from the linters

Bump ruff to 0.0.278 and fix new lint errors. I added noqa to all
existing RUF012 errors which requires mutable class variables to be
annotated with `ClassVar`, as well as all PERF issues.
