This commit adds tests that verify the current behavior wrt injector
tree traversal for downgraded components, so that it is easier to
contrast with changed behavior is future commits (should we decide
to actually change it).
PR Close#27217
Previously, nested downgraded components would not be created/destroyed
inside the Angular zone (as they should) and they would not be wired up
correctly for change detection.
This commit ensures that ngUpgrade correctly detects whether this is an
ngUpgradeLite app (i.e. one using `downgradeModule()` instead of
`UpgradeModule`) and appropriately handles components, even if they are
nested inside other downgraded components.

* We should try loading Angular.JS for the upgrade tests in their minfied output. There seems to be a lot flakiness in regards to loading `AngularJS` within Travis, and the `onerror` messages aren't really too helpful. In order to reduce the payload that will be passed through the Saucelabs tunnel, we should try to load the minfied output files.
PR Close#27711
Currently whenever the upgrade test helper fails to load a given AngularJS version, the error that will be rejected is technically not an error because the `onerror` callback is not returning an error, but an "ErrorEvent".
Since that `ErrorEvent` is basically just rejected, browsers will print
the error as followed:
```
Failed: [object Event]
```
This is not helpful at all and also implies that there _might_ be more
information hidden within the `Event` instance. Unfortunately that's not
the case (at least on browsers we test against) and the logic to extract
the data from the event would be not worth the effort, we just return a
simple custom `Error` that won't imply that there is more information
hidden.

In ngUpgrade (dynamic) we create a dynamic Angular `Directive` that wraps AngularJS components
that are being upgraded. The constructor of this `Directive` class returns a different instance
than `this`. It is this instance that actually contains the life-cycle hook handlers.
This would break in ivy, since the methods on the prototype of the original class are wired up,
rather than the instance methods. This results in hooks like `ngOnInit` not being called.
This commit refactors the code to extend the inner class that was being returned so that the
prototype chain is correct for both ViewEngine and ivy.
This change resolves a number of failing ivy tests, but also exposes other failures that were
masked by this issue. The tests have been updated accordingly.

`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.

Previously, if the two injectors are not the same, jasmine tried to
display an error message, but it got stuck in an infinite loop trying
to render the injectors that were different.

Make the error messages thrown when instantiating downgraded components,
injectables and modules more descriptive and actionable, also taking
into account incorrect use of the `downgradedModule` field.
PR Close#26217
Currently, calling `downgradeModule()` more than once is not supported.
If one wants to downgrade multiple Angular modules, they can create a
"super-module" that imports all the rest and downgrade that.
This commit adds support for downgrading multiple Angular modules. If
multiple modules are downgraded, then one must explicitly specify the
downgraded module that each downgraded component or injectable belongs
to, when calling `downgradeComponent()` and `downgradeInjectable()`
respectively.
No modification is needed (i.e. there is no need to specify a module for
downgraded components and injectables), if an app is not using
`downgradeModule()` or if there is only one downgraded Angular module.

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

With these changes, the types are a little stricter now and also not
compatible with Protractor's jasmine-like syntax. So, we have to also
use `@types/jasminewd2` for e2e tests (but not for non-e2e tests).
I also had to "augment" `@types/jasminewd2`, because the latest
typings from [DefinitelyTyped][1] do not reflect the fact that the
`jasminewd2` version (v2.1.0) currently used by Protractor supports
passing a `done` callback to a spec.

All errors for existing fields have been detected and suppressed with a
`!` assertion.
Issue/24571 is tracking proper clean up of those instances.
One-line change required in ivy/compilation.ts, because it appears that
the new syntax causes tsickle emitted node to no longer track their
original sourceFiles.

Changes would not propagate to a value in downgraded component in case you had two-way binding and listening to a value-change, e.g. [(value)]="value" (value-change)="fetch()"

Previously, when a downgraded component was destroyed in a way that did
not trigger the `$destroy` event on the element (e.g. when a parent
element was removed from the DOM by Angular, not AngularJS), the
`ComponentRef` was not destroyed and unregistered.
This commit fixes it by listening for the `$destroy` event on both the
element and the scope.

`packages/upgrade/static/src` is anymlink to `packages/upgrade/src`.
Still, using the correct paths (e.g. using
`@angular/upgrade/static/src/...` for `@angula/upgrade/static` specs
ensures that the module loader (e.g. SystemJS) can map the imports to
the same instances.
