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.
Example typings files:
```ts
declare class EmptyOutletComponent {
}
export {EmptyOutletComponent as ɵEmptyOutletComponent}
```
will be emitted as
```ts
export declare class ɵEmptyOutletComponent {
}
```

The `setUpLocationSync` function in @angular/router/upgrade didn't previously let you sync hash-based navigations. With this change, you can now pass an option to `setUpLocationSync` that will make sure location changes run in Angular in hash-based apps.

Since we build and publish the individual packages
using Bazel and `build.sh` has been removed, we can
safely remove the `rollup.config.js` files which are no
longer needed because the `ng_package` bazel rule
automatically handles the rollup settings and globals.

When a UrlTree of root url was returned by a guard as a redirection, the
navigation was not processed. The issue came from the error handler which
incorrectly marked the router as already navigated.

The value here is unimportant on initialization since it's not looked at until the second navigation. However, sometimes in testing the `Location` service is mocked out, or the Router constructor manually called. Assuming `Location` exists in the constructor leads to test failures in `google3` therefore we initialize to a value that will not cause errors.

With #27680, a bug was fixed where multiple redirects using `eager` URL update could cause navigation to fail. However, that fix introduced a problem where with `skipLocationChange` enabled, the URL tree rendered was not properly stored for reference. This specifically caused an issue with named router outlets and subsequent navigations not being recognized.
This PR stores the correct `UrlTree` for reference with later navigations. It fixes the regression introdued with #27680.

Previously when testing code injected the Compiler, it received the
top-level Compiler implementation defined in linker/compiler.ts
(and governed by the __PRE_R3__ switch). Code running under the
TestBed, however, should always use a TestBed-aware Compiler
implementation.
This commit adds such an implementation to the TestBedRender3,
which passes compiled modules through the _compileNgModule()
function.
With this change, 3 formerly disabled router integration tests
now pass.

Previously, we had the logic to schedule a change detection tick
inside markViewDirty(). This is fine when used in markDirty(),
the user-facing API, because it should always schedule change
detection. However, this doesn't work when used in markForCheck()
because historically markForCheck() does not trigger change
detection.
To be backwards compatible, this commit moves the scheduling
logic out of markViewDirty() and into markDirty(), so
markForCheck no longer triggers a tick.

Navigating to a route such as `/users`, you may get redirected to `/login`. Previously, if you go then route to `/users` again the URL will end up showing `/users` after the second redirect. This only happened in `UrlUpdateStrategy="eager"`. This is now fixed so after the second redirect, the URL shows the correct page.

This option means guards and resolvers will ignore changes when a provided predicate function returns `false`. This supports use cases where an application needs to ignore some param updates but not others. For example, changing a sort param in the URL might need to be ignored, whereas changing the a `project` param might require re-run of guards and resolvers.

It looks like `fixmeIvy` imports were accidentally removed from Router integration tests, thus causing build errors. The necessary imports are now restored and the project should build normally.

`NgModule` requires that `Component`s/`Directive`s/`Pipe`s are listed in
declarations, and that each `Component`s/`Directive`s/`Pipe` is declared
in exactly one `NgModule`. This change adds runtime checks to ensure
that these sementics are true at runtime.
There will need to be seperate set of checks for the AoT path of the
codebase to verify that same set of semantics hold. Due to current
design there does not seem to be an easy way to share the two checks
because JIT deal with references where as AoT deals with AST nodes.

This option means guards and resolvers will ignore changes to matrix parameters. Guards and resolvers will be rerun when the path changes, when path parameters change, or when query parameters change.
The primary use case for such a mode is when updating the UI and getting the URL to be in sync with local changes. For example, if displaying a sortable table, changing the sort direction is often handled by the table itself. But you would want to update the URL to be in sync with what's being displayed to the user. As long as the table sort direction is stored as a matrix parameter, you can use this option to update the URL without causing the overhead of re-running guards and resolvers.

BREAKING CHANGE:
The public API for `DebugNode` was accidentally too broad. This change removes
1. Public constructor. Since `DebugNode` is a way for Angular to communicate information
on to the developer there is no reason why the developer should ever need to
Instantiate the `DebugNode`
2. We are also removing `removeChild`, `addChild`, `insertBefore`, and `insertChildAfter`.
All of these methods are used by Angular to constructor the correct `DebugNode` tree.
There is no reason why the developer should ever be constructing a `DebugNode` tree
And these methods should have never been made public.
3. All properties have been change to `readonly` since `DebugNode` is used by Angular
to communicate to developer and there is no reason why these APIs should be writable.
While technically breaking change we don’t expect anyone to be effected by this change.

We are close enough to blacklist a few test targets, rather than whitelist targets to run...
Because bazel rules can be composed of other rules that don't inherit tags automatically,
I had to explicitly mark all of our ts_library and ng_module targes with "ivy-local" and
"ivy-jit" tags so that we can create a query that excludes all fixme- tagged targets even
if those targets are composed of other targets that don't inherit this tag.
This is the updated overview of ivy related bazel tags:
- ivy-only: target that builds or runs only under ivy
- fixme-ivy-jit: target that doesn't yet build or run under ivy with --compile=jit
- fixme-ivy-local: target that doesn't yet build or run under ivy with --compile=local
- no-ivy-jit: target that is not intended to build or run under ivy with --compile=jit
- no-ivy-local: target that is not intended to build or run under ivy with --compile=local

This is a major refactor of how the router previously worked. There are a couple major advantages of this refactor, and future work will be built on top of it.
First, we will no longer have multiple navigations running at the same time. Previously, a new navigation wouldn't cause the old navigation to be cancelled and cleaned up. Instead, multiple navigations could be going at once, and we imperatively checked that we were operating on the most current `router.navigationId` as we progressed through the Observable streams. This had some major faults, the biggest of which was async races where an ongoing async action could result in a redirect once the async action completed, but there was no way to guarantee there weren't also other redirects that would be queued up by other async actions. After this refactor, there's a single Observable stream that will get cleaned up each time a new navigation is requested.
Additionally, the individual pieces of routing have been pulled out into their own operators. While this was needed in order to create one continuous stream, it also will allow future improvements to the testing APIs as things such as Guards or Resolvers should now be able to be tested in much more isolation.
* Add the new `router.transitions` observable of the new `NavigationTransition` type to contain the transition information
* Update `router.navigations` to pipe off of `router.transitions`
* Re-write navigation Observable flow to a single configured stream
* Refactor `switchMap` instead of the previous `mergeMap` to ensure new navigations cause a cancellation and cleanup of already running navigations
* Wire in existing error and cancellation logic so cancellation matches previous behavior
