Use atomics for kwargs reference count
Fixes [Bug #22075] jhawthorn (John Hawthorn)
09:54 AM Ruby Bug #22075: heap-use-after-free in `rb_vm_ci_lookup` under parallel Ractors: Thank you for the reliable reproduction. I believe the issue is that `super` calls are duplicating callinfos, but the reference count for the kwargs array isn't using atomics.
```ruby
class Base
def foo(a:, b:, c:) = a
end
