CI: Update clang-tidy linter exclusion filter

Don't show an error on unknown NOLINT lines (presuming that someone is using a
newer version, etc.), nor formatting issues (which are handled outside the
linter). Clean up clazy checks to remove non-pod-static check, and to do the
Qt6 checks on main (instead of master)
