🗿 Rock-conaissance, also break config

The existing `ViewComponent::Config` object seems fit for purpose when it comes to component-local config, but I think what we want is:
- a `RailsAppConfig` object that's responsible for the things that will still need to be set against `Rails.application.config`
- a `ComponentLocalConfig` object that's effectively `ViewComponent::Config`. We should make sure that config is inheritable, and perhaps provide some kind of DSL to set it up, e.g.:

```rb
class ApplicationComponent < ViewComponent::Base
  configure do
    some_option true
    some_other_option "value"
  end
end
```
