refactor(router): Update recognize to use Observable instead of `…

…Promise` (#46021)

The `Observable` chain is currenlty the most straightforward way to
handle navigation cancellations where we ensure that the cancelled
navigation does not continue to be processed. Until we design and
implement an alternative way to accomplish equivalent functionality,
we need to maintain the `Observable` chain wherever we might execute
user code. One reason for this isthat user code may contain redirects so we do not
want to execute those redirects if the navigation was already cancelled.
