BREAKING CHANGE:
We no longer directly have a direct depedency on `tslib`. Instead it is now listed a `peerDependency`.
Users not using the CLI will need to manually install `tslib` via;
```
yarn add tslib
```
or
```
npm install tslib --save
```

Component defs are not considered public API, so the property
that contains them should be prefixed with Angular's marker
for "private" ('ɵ') to discourage apps from relying on def
APIs directly.
This commit adds the prefix and shortens the name from
`ngComponentDef` to `cmp`. This is because property names
cannot be minified by Uglify without turning on property
mangling (which most apps have turned off) and are thus
size-sensitive.
Note that the other "defs" (ngDirectiveDef, etc) will be
prefixed and shortened in follow-up PRs, in an attempt to
limit how large and conflict-y this change is.

In View Engine, animation metadata could occur in nested arrays which
would be flattened in the compiler. When compiling a component for Ivy
however, the compiler no longer statically evaluates a component's
animation metadata and is therefore unable to flatten it statically.
This resulted in an issue to find animations at runtime, as the metadata
was incorrectly registered with the animation engine.
Although it would be possible to statically evaluate the animation
metadata in ngtsc, doing so would prevent reusable animations exported
from libraries from being usable as ngtsc's partial evaluator is unable
to read values inside libraries. This is unlike ngc's usage of static
symbols represented in a library's `.metadata.json`, which explains how
the View Engine compiler is able to flatten the animation metadata
statically.
As an alternative solution, the metadata flattening is now done in the
runtime during the registration of the animation metadata with the
animation engine.

Logs a warning instead of throwing when running into a binding to an unknown property in JIT mode. Since we aren't using a schema for the runtime validation anymore, this allows us to support browsers where properties are unsupported.

Currently, it's not possible to tree-shake away the
coordination layer between HammerJS and Angular's
EventManager. This means that you get the HammerJS
support code in your production bundle whether or
not you actually use the library.
This commit removes the Hammer providers from the
default platform_browser providers list and instead
provides them as part of a `HammerModule`. Apps on
Ivy just need to import the `HammerModule` at root
to turn on Hammer support. Otherwise all Hammer code
will tree-shake away. View Engine apps will require
no change.
BREAKING CHANGE
Previously, in Ivy applications, Hammer providers
were included by default. With this commit, apps
that want Hammer support must import `HammerModule`
in their root module.

In VE the `Sanitizer` is always available in `BrowserModule` because the VE retrieves it using injection.
In Ivy the injection is optional and we have instructions instead of component definition arrays. The implication of this is that in Ivy the instructions can pull in the sanitizer only when they are working with a property which is known to be unsafe. Because the Injection is optional this works even if no Sanitizer is present. So in Ivy we first use the sanitizer which is pulled in by the instruction, unless one is available through the `Injector` then we use that one instead.
This PR does few things:
1) It makes `Sanitizer` optional in Ivy.
2) It makes `DomSanitizer` tree shakable.
3) It aligns the semantics of Ivy `Sanitizer` with that of the Ivy sanitization rules.
4) It refactors `DomSanitizer` to use same functions as Ivy sanitization for consistency.

Fixes Ivy's `DebugElement.triggerEventHandler` to picking up events that have been registered through a `Renderer2`, unlike ViewEngine.
This PR resolves FW-1480.
PR Close#31845
Currently developers can use the `By` class to construct common
`DebugElement` query predicates. e.g. `By.directive(MyDirective)`.
The `directive()` and `all()` predicates are currently returning
a predicate that works for `DebugElement` nodes. This return type
is too strict since the predicate is not specific to `DebugElement`
instances and can also apply to `DebugNode` instances.
Meaning that developers are currently able to use the `directive()`
predicate when using `queryAllNodes()`. This is a common practice
but will break when the project is compiled with TypeScript's
`--strictFunctionTypes` flag as the `DebugElement` predicate type
is not assignable to predicates for `DebugNode`. In order to make
these predicates usable with `--strictFuntionTypes` enabled, we
adjust the predicate type to reflect what is actually needed for
evaluation of the predicate.

Fixes all TypeScript failures caused by enabling the `--strict`
flag for test source files. We also want to enable the strict
options for tests as the strictness enforcement improves the
overall codehealth, unveiled common issues and additionally it
allows us to enable `strict` in the `tsconfig.json` that is picked
up by IDE's.

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.

BREAKING CHANGE
In PR #19558, we fixed a bug in `TestBed.overrideProvider` where
eager providers were not being instantiated correctly. However,
it turned out that since this bug had been around for quite a bit,
many apps were relying on the broken behavior where the providers
would not be instantiated. To assist in the transition, the
`TestBed.deprecatedOverrideProvider` method was temporarily
introduced to mimic the old behavior so that apps would have a
longer time period to migrate their code.
2 years and 3 versions later, it is time to remove the temporary
method. This commit removes `TestBed.deprecatedOverrideProvider`
altogether. Any usages of `TestBed.deprecatedOverrideProvider`
should be replaced with `TestBed.overrideProvider`. This may mean
that providers that were not created before will now be instantiated,
which could mean that your tests need to provide more mocks or stubs
for the dependencies of the newly instantiated providers.

There is an encoding issue with using delta `Δ`, where the browser will attempt to detect the file encoding if the character set is not explicitly declared on a `<script/>` tag, and Chrome will find the `Δ` character and decide it is window-1252 encoding, which misinterprets the `Δ` character to be some other character that is not a valid JS identifier character
So back to the frog eyes we go.

Ivy uses R3Injector, but we are currently pulling in both the StaticInjector
(View Engine injector) and the R3Injector when running with Ivy. This commit
adds an ivy switch so calling Injector.create() pulls in the correct
implementation of the injector depending on whether you are using VE or Ivy.
This saves us about 3KB in the bundle.

Prior to this commit, we were pulling DebugNode and DebugElement
into production builds because BrowserModule automatically pulled
in NgProbe and thus getDebugNode. In Ivy, this is not necessary
because Ivy has its own set of debug utilities. We should use these
existing tools instead of NgProbe.
This commit adds an Ivy switch so we do not pull in NgProbe utilities
when running with Ivy. This saves us ~8KB in prod builds.
