Title: Extract ActionDispatch::Request#deep_munge

`ActionDispatch::Request#deep_munge` was introduced as a private method, but was turned into a public one for the use of `ActionDispatch::ParamsParser`.

I have extracted it into `ActionDispatch::Request::Utils`, so it does not get mixed up with the `ActionDispatch::Request` public methods.
