Make zone handlers call zone.run to run callbacks. (#2451)

The platform library `Zone` implementation will change to not use
`bindCallbackGuarded` in the `Timer` constructors and top-level
`scheduleMicrotask` function.
Instead it only calls `registerCallback`, and then the
`Zone.create{,Periodic}Timer` and `Zone.scheduleMicrotask` are in charge
of using `Zone.runGuarded` on the callback when timer/microtask event
happens.

This ensures that a surrounding zone's `registerCallback` can't make the
callback throw in a way that is outside of the `runGuarded` call.

Also makes periodic timers that are delayed past multiple tick points,
update their `tick` count by more than one instead of running multiple
times, like timers should.

Adds testing of using the `FakeAsync`'s `Zone` functions directly, and
embedding it in another zone to check that it does run using `Zone.run`.
Adds testing of periodic timers incrementing `tick` by more than one.
