1. Move the plumbing of the URL handling to private APIs in QtCore, used by QDesktopServices
2a. Add a helper QOAuth2AuthorizationCodeFlow::openChallengeUrl function that uses the QtCore private api
2b. Have QOAuth2AuthorizationCodeFlow automatically open the browser via the QtCore private API

No public API changes needed to QDesktopServices needed, which means we’re not blocking the QtNetworkAuth work on the work required to research activities/intents APIs (which is not scheduled for 6.8).
