Support for Accessing Authorization Response Parameters for response_mode=form_post Implementation

[arif-basri]

This PR adds logic to expose the authorization response parameters (uri_params['query']) in the AuthorizeController. This change enables downstream controller code to access these parameters, which is helpful for implementing the OAuth2 response_mode=form_post specification. With this update, the controller can handle form post responses by utilizing the parameters directly, improving standards compliance and flexibility for different response modes.

Otherwise we need to parse the redirect url for the parameters which is not elegant.
