When we have an event listener inside an embedded view, we generate a `restoreView` call which saves the view inside of the LFrame. The problem is that we don't clear it until it gets overwritten which can lead to memory leaks.
These changes rework the generated code in order to generate a `resetView` call which will clear the view from the LFrame.

Angular contains an NgModule registry, which allows a user to declare
NgModules with string ids and retrieve them via those ids, using the
`getNgModuleById` API.
Previously, we attempted to structure this registration in a clever fashion
to allow for tree-shaking of registered NgModules (that is, those with ids).
This sort of worked due to the accidental alignment of behaviors from the
different tree-shakers involved. However, this trick relies on the
generation of `.ngfactory` files and how they're specifically processed in
various bundling scenarios. We intend to remove `.ngfactory` files, hence
we can no longer rely on them in this way.
The correct solution here is to recognize that `@NgModule({id})` is
inherently declaring a global side-effect, and such classes should not
really be eligible for tree-shaking in the first place. This commit removes
all the old registration machinery, and standardizes on generating a side-
effectful call to `registerNgModuleType` for NgModules that have ids.
There is some risk here that NgModules with unnecessary `id`s may not
tree-shake as a result of this change, whereas they would have in previous
circumstances. The fix here should be to remove the `id` if it's not needed.
Specifying an `id` is a request that the NgModule be retained regardless of
any other references, in case it is later looked up by string id.

The animations package supports adding default parameter values to an animation that will be used as a fallback if some parameters aren't defined. The problem is that they're applied using a spread expression which means that any own property of the animation parameters will override the defaults, even if it resolves to null or undefined. This can lead to obscure errors like "Cannot read property toString of undefined" for an animation that looks like `{params: {foo: undefined}}` with defaults `{foo: 123}`.
I ran into this issue while debugging some test failures on Material.
These changes address the issue by:
1. Applying the defaults if the resolved value is null or undefined.
2. Updating the validation function to use a null check instead of `hasOwnProperty`.

model.ts is currently extremely large. This is the first step in an attempt to refactor it to be more easily navigable and reviewable. This commit breaks up `model.ts` into the following new files:
* `model/abstract_model.ts`: The remainder of the model, including the `AbstractControl` base class and helper functions which are used throughout.
* `model/form_control.ts`: `FormControl`, `FormControlOptions`, and helpers, plus the constructor and untyped friends.
* `model/form_array.ts`: `FormArray` and untyped friends.
* `model/form_group.ts`: `FormGroup` and untyped friends.
This first phase is a purely mechanical code move. There is no new code at all, and no interfaces have been separated.

These changes combine #41358 and #41894.
Currently we save a reference to an `LView` on most DOM nodes created by Angular either by saving the `LView` directly in the `__ngContext__` or by saving the `LContext` which has a reference to the `LView`. This can be a problem if the DOM node is retained in memory, because the `LView` has references to all of the child nodes of the view, as well as other internal data structures.
Previously we tried to resolve the issue by clearing the `__ngContext__` when a node is removed (see https://github.com/angular/angular/pull/36011), but we decided not to proceeed, because it can slow down destruction due to a megamorphic write.
These changes aim to address the issue while reducing the performance impact by assigning a unique ID when an `LView` is created and adding it to `__ngContext__`. All active views are tracked in a map where their unique ID is used as the key. We don't need to worry about leaks within that map, because `LView`s are an internal data structure and we have complete control over when they are created and destroyed.

The prior approach would consider all existing namespaces from back to front
to find the one that's the closest ancestor for a given host element. An

an optimization where the closest namespace is found by traversing up from

Before Ivy, it was only possible to call the `ViewContainerRef.createComponent` function with the ComponentFactory as the first argument. An instance of a `ComponentFactory` resolved via `ComponentFactoryResolver` contained a reference to an `NgModule` where the component is declared. As a result, the component maintained a DI connection with the module injector tree (by retrieving an instance of `NgModuleRef` internally), even when the custom injector was provided (we try to find a token in a custom injector first and consult module injector after that).
With Ivy, we expanded the `ViewContainerRef.createComponent` function API to support direct references to the Component classes without going through the factory resolution step. As a result, there was no connection to the NgModule that declares the component. Thus, if you provide a custom injector, this is the only injector that is taken into account.
This commit updates the logic for the factory-less case to try retrieving an instance of an `NgModuleRef` using the DI tree which `ViewContainerRef` belongs to. The `NgModuleRef` instance is then used to get a hold of a module injector tree. This brings the factory-less and factory-based logic to more consistent state.

This commit provides a service, `PageTitleStrategy` for setting
the document page title after a successful router navigation.
Users can provide custom strategies by extending `TitleStrategy` and
adding a provider which overrides it.
The strategy takes advantage of the pre-existing `data` and `resolve` concepts
in the Router implementation:
We can copy the `Route.title` into `data`/`resolve` in a
non-breaking way by using a `symbol` as the key. This ensures that we
do not have any collisions with pre-existing property names. By using
`data` and `resolve`, we do not have to add anything more to
the router navigation pipeline to support this feature.

When running tests with code coverage using Istanbul, the code is
instrumented with coverage reporting statements. These statements are
also inserted into synthesized constructors, preventing Angular from
properly recognizing them as synthesized constructor.
This commit changes the regex to detect synthesized constructors to allow
for statements within the constructor before the `super(...arguments);`
call. This is limited to code that does not contain a `}`, but this
is sufficient to support Istanbul's coverage instrumentation statements.
The tests have been extended with an input file that is being
instrumented using `babel-plugin-istanbul` for both ES2015 and ES5
targets, in order to verify that the approach works for real-world
usages.

`Renderer2` APIs expect to be called with the namespace name rather than
the namespace URI. Rather than passing around the URI and having to
account for different calling contexts, this change consistently uses
the namespace short names.
Importantly, the URI was only used in `component_ref.ts` `create`
(because `getNamespace returned the URIs`) and `createElementNode` in
`node_manipulation.ts` (because `getNamespaceUri` also used the URIs).
In contrast, attributes would use the _short names instead of URIs_
(see `setUpAttributes` in `attrs_utils.ts`). These names are pulled
directly from the attribute, i.e. `xhtml:href` and not converted to URI.
This dichotomy is confusing and unnecessary. The change here aligns the two
approaches in order to provide consistently throughout the system.
This relates to #44766 because the `createElementNode` was calling the
`AnimationRenderer.createElement` which delegates to the
`ServerRenderer`, which in turn was only set up to expect short names.
As a result, the `NAMESPACE_URIS` lookup failed and `Domino` created
the `svg` as a regular `Element` which does not have a `styles`
property.

when reordering a list with animations the list items lose their current
triggers values, that is because the reordering of an item is implemented
as follows (_note:_ the following implementation has been added in PR #23534)
- the item is removed and marked _setForRemoval_
- the item is re-inserted, and the _setForRemoval_ is changed to _setForMove_
- the player set for animating the removal is destroyed when _setForMove_ is detected
the above steps allow the element not to be animated and to keep its styling but the
triggers values get lost since the removal transition/player has already been initialized,
so this change adds a _previousTriggersValues_ map in the _REMOVAL_FLAG_ field in order to
restore the triggers values if/when the removal turns out to be a move, changing the above steps to:
- the item is removed and marked setForRemoval __and its current triggers values are saved as well__
- the item is re-inserted, and the setForRemoval is changed to setForMove
- the player set for animating the removal is destroyed when setForMove is detected __and the
trigger values are re-applied in the engine's statesByElement map__
