DOM: Implement the switchMap() Observable operator

See https://github.com/WICG/observable/pull/130 for the spec PR, and
https://chromium-review.googlesource.com/c/chromium/src/+/5381640 for
documentation about the flatMap() operator, which is structured in
almost the same way as switchMap().

New Tests That Don't Pass

    • switchMap(): result subscribes to one inner observable at a time, unsubscribing from the previous active one when a new one replaces it: FAIL (Safari: FAIL)
    • switchMap(): result does not complete when the source observable completes, if the inner observable is still active: FAIL (Safari: FAIL)
    • switchMap(): result emits an error if Mapper callback throws an error: FAIL (Safari: FAIL)
    • switchMap(): result emits an error if the source observable emits an error: FAIL (Safari: FAIL)
    • switchMap(): result emits an error if the inner observable emits an error: FAIL (Safari: FAIL)
    • switchMap(): should unsubscribe in the correct order when user aborts the subscription: FAIL (Safari: FAIL)
