Resubmit #31168 now that google3 tests can pass. This requires http://cl/272696717 to be patched.
Original description from jasonaden:
Without this change when using UrlTree redirects in urlUpdateStrategy="eager", the URL would get
updated to the target location, then redirected. This resulted in having an additional entry in the
history and thus the back button would be broken (going back would land on the URL causing a new
redirect).
Additionally, there was a bug where the redirect, even without urlUpdateStrategy="eager", could
create a history with too many entries. This was due to kicking off a new navigation within the
navigation cancelling logic. With this PR the new navigation is pushed to the next tick with a
setTimeout, allowing the page being redirected from to be cancelled before starting a new
navigation.

There is some confusion around which `NavigationExtras` values are used
by createUrlTree. This specifies that only values that change the URL
are used. This came up during the discussion in #27148.

`InitialNavigation` is used in `ExtraOptions`, which is already part of
the public API. Thus, `InitialNavigation` should be too. Not publicly
exporting it from `router/index.ts` seems an omission, since the type is
already annotated with the `@publicApi` JSDoc tag.
By publicly exporting `InitialNavigation`, it will also correctly appear
in the API docs on angular.io.

PR #30393 corrected behavior where Object.keys sometimes returns an `undefined` value. However, the types didn't reflect this in the code. That fix actually missed one value that could return `undefined`. This PR corrects this by casting the types to what they can be in IE 11. This ensures the code behaves as it should when this edge case comes up.

In some cases where multiple navigations happen to the same URL, the router will not process a given URL. In those cases, we fall into logic that resets state for the next navigation. One piece of this resetting is to set the `browserUrlTree` to the most recent `urlAfterRedirects`i.
However, there was bug in this logic because in some cases the `urlAfterRedirects` is a stale value. This happens any time a URL won't be processed, and the previous URL will also not be processed. This creates unpredictable behavior, not the least of which ends up being a broken `back` button.
This PR kicks off new navigations with the current value the router assumes is in the browser. All the logic around how to handle future navigations is based on this value compared to the current transition, so it's important to kick off all new navigations with the current value so in the edge case described above we don't end up with an old value being set into `browserUrlTree`.

This PR fixes an issue where IE 11 can return `undefined` in with an `Object.keys` call. Solution is to add a runtime check on the value. Based on the types being passed, this shouldn't be necessary, but is needed only for IE 11. Unit test doesn't work for this PR because it can't be replicated easily.

There was a problem with a combination of the `eager` URL update, browser `back` button, and hybrid applications. Details provided in internal ticket http://b/123667227.
This fix handles the problem by setting `router.browserUrlTree` when all conditions have failed, meaning the browser doesn't do anything with the navigation other than update internal data structures. Without this change, the problem was an old value was stored in `router.broserUrlTree` causing some new navigations to be compared to an old value and breaking future navigations.

The proposed ES dynamic import() is now supported by the Angular CLI and the
larger toolchain. This renders the `loadChildren: string` API largely
redundant, as import() is far more natural, is less error-prone, and is
standards compliant. This commit deprecates the `string` form of
`loadChildren` in favor of dynamic import().
DEPRECATION:
When defining lazy-loaded route, Angular previously offered two options for
configuring the module to be loaded, both via the `loadChildren` parameter
of the route. Most Angular developers are familiar withthe `string` form of
this API. For example, the following route definition configures Angular to
load a `LazyModule` NgModule from `lazy-route/lazy.module.ts`:
```
[{
path: 'lazy',
loadChildren: 'lazy-route/lazy.module#LazyModule',
}]
```
This "magic string" configuration was previously necessary as there was
no dynamic module loading standard on the web. This has changed with the
pending standardization of dynamic `import()` expressions, which are now
supported in the Angular CLI and in web tooling in general. `import()`
offers a more natural and robust solution to dynamic module loading. The
above example can be rewritten to use dynamic `import()`:
```
[{
path: 'lazy',
loadChildren: () => import('./lazy-route/lazy.module').then(mod => mod.LazyModule),
}]
```
This form of lazy loading offers significant advantages in terms of:
* type checking via TypeScript
* simplicity of generated code
* future potential to run natively in supporting browsers
(see: [caniuse: dynamic import()](https://caniuse.com/#feat=es6-module-dynamic-import))
As a result, Angular is deprecating the `loadChildren: string` syntax in
favor of ES dynamic `import()`. An automatic migration will run during
`ng upgrade` to convert your existing Angular code to the new syntax.

Prior to this change, if a navigation was ongoing and a new one came in, the router could get into a state where `router.currentNavigation` was `null` even though a navigation was executing. This change moves where we set the `currentNavigation` value so it's inside a `switchMap`. This solves the problem because the `finally` on the `switchMap` had been setting `currentNavigation` to `null` but the new `currentNavigation` value would have already been set. Essentially this was a timing problem and is resolved with this change.

This PR also changes the name of `EmptyOutletComponent` to `ɵEmptyOutletComponent`. This is because `ngcc` requires the node to retain the original name while dts bundler will rename the node is it's only exported using the aliases.

```ts

}
export {EmptyOutletComponent as ɵEmptyOutletComponent}
```
will be emitted as
