- Fixes https://github.com/oxc-project/oxc/issues/5406
This implements a fix for the `BindingRestElement` symbol, which is
currently unhandled and gets automatically marked as unused. If we
happen to find that it is a child of declaration, then we will
automatically allow the binding rest element.
The code for this was based on what we currently do in
`is_allowed_param_because_of_method`:
5187f384cb/crates/oxc_linter/src/rules/eslint/no_unused_vars/allowed.rs (L258)
I opted not to refactor this to re-use the same code though, as I think
the duplication is still incidental and the implementations could
diverge in the future.
