[ruff] Omit diagnostic for shadowed private function parameters in used-dummy-variable (RUF052)

[dylwil3]

As discussed in #14818, we should skip used-dummy-variable (RUF052) for private function parameters. This PR extends the logic from loc. cit. and further skips the lint for bindings in the body of a function which shadow a private function parameter.

Closes #14968
