This is a pre-requisite for #40360. Given the following template which has a listener
that references a variable from a parent template (`name`):
```
<ng-template let-name="name">
<button (click)="hello(name)"></button>
</ng-template>
```
We generate code that looks that looks like. Note how we access `name` through `ctx`:
```js
function template(rf, ctx) {
if (rf & 1) {
const r0 = ɵɵgetCurrentView();
ɵɵelementStart(0, "button", 2);
ɵɵlistener("click", function() {
ɵɵrestoreView(r0);
const name_r0 = ctx.name; // Note the `ctx.name` access here.
const ctx_r1 = ɵɵnextContext();
return ctx_r1.log(name_r0);
});
ɵɵelementEnd();
}
}
```
This works fine at the moment, because the template context object can't be changed after creation.
The changes in #40360 allow for the object to be changed, which means that the `ctx` reference
inside the listener will be out of date, because it was bound during creation mode.
This PR aims to address the issue by accessing the context inside listeners through the saved
view reference. With the new code, the generated code from above will look as follows:
```js
function template(rf, ctx) {
if (rf & 1) {
const r0 = ɵɵgetCurrentView();
ɵɵelementStart(0, "button", 2);
ɵɵlistener("click", function() {
const restoredCtx = ɵɵrestoreView(r0);
const name_r0 = restoredCtx.name;
const ctx_r1 = ɵɵnextContext();
return ctx_r1.log(name_r0);
});
ɵɵelementEnd();
}
}
```

This commit adds `ngDevMode` guard to show the warning only
in dev mode (similar to how things work in other parts of Ivy runtime code).
The `ngDevMode` flag helps to tree-shake the warning from production builds
(in dev mode everything will work as it works right now) to decrease production bundle size.

Our approach for handling cyclic imports results in code that is
not easy to tree-shake, so it is not suitable for publishing in a
library.
When compiling in partial compilation mode, we are targeting
such library publication, so we now create a fatal diagnostic
error instead of trying to handle the cyclic import situation.

ChromeDriver now supports Apple Silicon ARM processors.
`webdriver-manager` versions 12.1.7 and earlier will, however,
incorrectly download the arm64 ChromeDriver regardless of the
system's architecture. This results in failure to run Protractor tests
on macOS with the error: `spawn Unknown system error -86`
This commit fixes the problem by upgrading `webdriver-manager` to
version 12.1.8, which includes a fix.

This commit adds the `emitEvent` option to the following FormArray and FormGroup methods:
* FormGroup.addControl
* FormGroup.removeControl
* FormGroup.setControl
* FormArray.push
* FormArray.insert
* FormArray.removeAt
* FormArray.setControl
* FormArray.clear
This option can be used to prevent an event from being emitted when adding or removing controls.
BREAKING CHANGE:
The `emitEvent` option was added to the following `FormArray` and `FormGroup` methods:
* FormGroup.addControl
* FormGroup.removeControl
* FormGroup.setControl
* FormArray.push
* FormArray.insert
* FormArray.removeAt
* FormArray.setControl
* FormArray.clear
If your app has custom classes that extend `FormArray` or `FormGroup` classes and override the
above-mentioned methods, you may need to update your implementation to take the new options into
account and make sure that overrides are compatible from a types perspective.

The previous commits refactored the `ShadowCss` emulator to support
desirable use-cases of `:host-context()`, but it dropped support
for passing a comma separated list of selectors to the `:host-context()` .
This commit rectifies that omission, despite the use-case not being
valid according to the ShadowDOM spec, to ensure backward compatibility
with the previous implementation.

In `ViewEncapsulation.Emulated` mode the compiler converts `:host` and
`:host-context` pseudo classes into new CSS selectors.
Previously, when there was both `:host-context` and `:host` classes in a
selector, the compiler was generating incorrect selectors. There are two
scenarios:
* Both classes are on the same element (i.e. not separated). E.g.
`:host-context(.foo):host(.bar)`. This setup should only match the
host element if it has both `foo` and `bar` classes. So the generated
CSS selector should be: `.foo.bar<hostmarker>`.
* The `:host` class is on a descendant of the `:host-context`. E.g.
`:host-context(.foo) :host(.bar)`. This setup should only match the
`.foo` selector if it is a proper ancestor of the host (and not on the
host itself). So the generated CSS selector should be:
`.foo .bar<hostmarker>`.
This commit fixes the generation to handle these scenarios.

In `ViewEncapsulation.Emulated` mode, the compiler must generate additional
combinations of selectors to handle the `:host-context()` pseudo-class function.
Previously, when there is was more than one `:host-context()` selector in a
rule, the compiler was generating invalid selectors.
This commit generates all possible combinations of selectors needed to
match the same elements as the native `:host-context()` selector.

On larger screens the top-bar has a height of 64px. On screens smaller
than 600px, the top-bar has a height of 56px. As a result, the sidenav
should have a top position of 56px on screens smaller than 600px and
64px on other screens.
Previously, the style setting the top position to 56px was tied to the
presence of the `.collapsed` class, which depends on whether the sidenav
is docked or not. The change from docked to collapsed sidenav, however,
happens at 992px. As a result, the sidenav had an incorrect top position
(56px instead of 64px) on screens between 600px and 991px.
This commit fixes this by ensuring the change of the top position for
the sidenav happens at 600px.

Both `CodeExampleComponent` and `CodeTabsComponent` components receive

This commit fixes this by clearing the projected DOM nodes once their

The "Usage Notes" section is often at the bottom of a long page of content
which can make it difficult to discover. This commit adds a link at the
end of the "Description" if there is a "Usage Notes" section on the page.
This link should help the reader to discover that there is more information
available further down the page.
This is basically a marginal fix. The longer term fix should be to
consider what content goes in which sections and how they should

In Chrome 83 passing a TrustedScript to eval just returns the
TrustedScript back without evaluating it, causing the
newTrustedFunctionFor{Dev,JIT} functions to fail. This is a browser bug
that has been fixed in Chrome 84, and only affects Angular applications
running with JIT (which includes unit tests).
As a temporary workaround for users still on Chrome 83, detect when this
occurs in the newTrustedFunctionFor* functions and fall back to the
straightforward, non-Trusted Types compatible implementation. The only
combination that is left affected consists of Angular applications
running with JIT, that have explicitly configured Trusted Types in
enforcement mode, with users that are still on Chrome 83.
Also correct docstring for newTrustedFunctionForJIT.
