feat: add will-redirect (#13866)

* feat: add will-redirect to allow people to prevent 30X redirects

* spec: add tests for the will-redirect event

* refactor: implement will-redirect using NavigationThrottle instead of PostTask

This avoids a potential race condition and immediately cancels the
navigation

* docs: add docs for did-redirect-navigation

* refactor: move AtomNavigationThrottle out of net folder

* refactor: update header guard for atom_navigation_throttle.h

* refactor: fix chromium style errors in the GN build

* refactor: update throttle impl to NOTREACHED and std::make_unqique
