This commit introduces a new subscription in the `routerLinkActive` directive which triggers an update
when any of its associated routerLinks have changes. `RouterLinkActive` not only needs to know when
links are added or removed, but it also needs to know about if a link it already knows about
changes in some way.
Quick note that `from...mergeAll` is used instead of just a simple
`merge` (or `scheduled...mergeAll`) to avoid introducing new rxjs
operators in order to keep bundle size down.

Previously, the `ngOnDestroy` method called `unsubscribe` regardless of if `subscription` had
been initialized. This can lead to an error attempting to call `unsubscribe` of undefined.
This change prevents this error, and instead only attempts `unsubscribe` when the subscription
has been defined.

When using the routerLinkActive directive inside a component that is using ChangeDetectionStrategy.OnPush and lazy loaded module routes the routerLinkActive directive does not update after clicking a link to a lazy loaded route that has not already been loaded.
Also the OnPush nav component does not set routerLinkActive correctly when the default route loads, the non-OnPush nav component works fine.

This PR changes the logic for determining when to skip route processing from
using the URL of the last attempted navigation to the actual resulting URL after
that transition.
Because guards may prevent navigation and reset the browser URL, the raw
URL of the previous transition may not match the actual URL of the
browser at the end of the navigation process. For that reason, we need to use
`urlAfterRedirects` instead.
Other notes:
These checks in scheduleNavigation were added in https://github.com/angular/angular/commit/eb2ceff4ba19a09a5f400f81e371ec176878cd37
The test still passes and, more surprisingly, passes if the checks are removed
completely. There have likely been changes to the navigation handling that
handle the test in a different way. That said, it still appears to be important
to keep the checks there in some capacity because it does affect how many
navigation events occur. This addresses an issue that came up in #16710: https://github.com/angular/angular/issues/16710#issuecomment-634869739
This also partially addresses #13586 in fixing history for imperative
navigations that are cancelled by guards.

This change aligns behavior for resolvers which return EMPTY. Currently EMPTY resolvers have inconsistent behavior:
- One resolver that returns EMPTY => won't navigate and just ends on ResolveStart router event.
- Two resolvers where both return EMPTY => throws "Error: Uncaught (in promise): EmptyError: no elements in sequence"
- Two resolvers where one returns a value and the other one returns EMPTY => Navigates successfully.
With this change any EMPTY resolver will cancel navigation.
BREAKING CHANGE: Any resolver which return EMPTY will cancel navigation.
If you want to allow the navigation to continue, you will need to update the resolvers to emit
some value, (i.e. defaultIfEmpty(...), of(...), etc).

A CanLoad guard returning UrlTree cancels current navigation and redirects.
This matches the behavior available to `CanActivate` guards added in #26521.
Note that this does not affect preloading. A `CanLoad` guard blocks any
preloading. That is, any route with a `CanLoad` guard is not preloaded
and the guards are not executed as part of preloading.

The major one that affects the angular repo is the removal of the bootstrap attribute in nodejs_binary, nodejs_test and jasmine_node_test in favor of using templated_args --node_options=--require=/path/to/script. The side-effect of this is that the bootstrap script does not get the require.resolve patches with explicitly loading the targets _loader.js file.

Currently we only run Saucelabs on PRs using the legacy View Engine
build. Switching that build to Ivy is not trivial and there are various
options:
1. Updating the R3 switches to use POST_R3 by default. At first glance,
this doesn't look easy because the current ngtsc switch logic seems to
be unidirectional (only PRE_R3 to POST_R3).
2. Updating the legacy setup to run with Ivy. This sounds like the easiest
solution at first.. but it turns out to be way more complicated. Packages
would need to be built with ngtsc using legacy tools (i.e. first building
the compiler-cli; and then building packages) and View Engine only tests
would need to be determined and filtered out. Basically it will result in
re-auditing all test targets. This is contradictory to the fact that we have
this information in Bazel already.
3. Creating a new job that runs tests on Saucelabs with Bazel. We specify
fine-grained test targets that should run. This would be a good start
(e.g. acceptance tests) and also would mean that we do not continue maintaining
the legacy setup..
This commit implements the third option as it allows us to move forward
with the general Bazel migration. We don't want to spend too much time
on our legacy setup since it will be removed anyway in the future.

Under bazel and Ivy we don't need the shim files to be emmited by default.
We still need to the shims for blaze however because google3 code imports them.
This improves build latency by 1-2 seconds per ng_module target.

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.

This commit makes the static flag on @ViewChild and @ContentChild required.
BREAKING CHANGE:
In Angular version 8, it's required that all @ViewChild and @ContentChild
queries have a 'static' flag specifying whether the query is 'static' or
'dynamic'. The compiler previously sorted queries automatically, but in
8.0 developers are required to explicitly specify which behavior is wanted.
This is a temporary requirement as part of a migration; see
https://angular.io/guide/static-query-migration for more details.
@ViewChildren and @ContentChildren queries are always dynamic, and so are
unaffected.
