The getting-started tutorial at angular.io/start instructs users to
generate a `ProductAlertsComponent` using the "Angular generator"
feature in [StackBlitz](https://stackblitz.com/). However, unlike the
Angular CLI, generating a component in StackBlitz does not automatically
declare it in `AppModule`, which is a requirement for the component to
be used in the application. This resulted in a compile error when
following the tutorial instructions.
This commit fixes this by adding a step to manually import and declare
the newly generated component in `app.module.ts`.

Add an abstract class that has a default implementation of the run
function and visits all nodes. Authors of template checks can extend
this class and override the `visitNode` method to return diagnostics.

Currently the error message functions are defined as static methods on a class which means that as soon as one of them is used somewhere, all of them have to be retained. This isn't a problem at the moment, because all of them are behind `ngDevMode` checks, but it's error prone and it's easy to fix.
These changes move them out into functions so that they can be imported individually. It also has the advantage of allowing Webpack to minify the function names.

The current naming causes tsickle to emit `/** @implements {ZoneDelegate} */ class ZoneDelegate ...`, which is a cyclic definition error in Closure Compiler. Additionally, the name shadowing is also confusing to humans.

Previously, the decorator transformer was annotating the synthesized properties with TS type annotations. However, because it ran after the JSDoc transformer, the TS types were just dropped from the emitted JS. Attempting to move the decorator transformer before the JSDoc transformer causes tsickle crashes because synthetic AST fragments are not attached to a SourceFile node.

Add a test to make sure extended template diagnostics are being correctly
generated in the language service for non-ts files.

Add the call to get the extended template diagnostics in
the compiler's `getDiagnosticsForComponent`. This makes showing
extended diagnostics in non-ts files posible.

Rename `getExtendedTemplateDiagnosticsForComponent` to
`getDiagnosticsForComponent` since it's implied they are extended
diagnostics.

Return `TemplateDiagnostic` instead of `ts.Diagnostic` when getting the
extended template diagnostics. This makes the integration with the
language service easier. This also fixes the error code and now uses the
`ngErrorCode` for extended template diagnostics.

This commit adds extended template diagnostics end-to-end tests, to make

This commit integrates extended template checks with the compiler, by
adding another phase of diagnostics generation. This integration is
under the `_extendedTemplateDiagnostics` flag.

This commit exports the implementation of `ExtendedTemplateChecker` to
generate extended template diagnostics and all the template checks.

Change the current way to run template checks to the
`ExtendedTemplateChecker` instead of just the
`getExtendedTemplateDiagnosticsForComponent` function. Refactored the
tests that used the previous function to use the new class.

The server transition initializer looks for some `style` tags and clears them based on their `ng-transition` ID. The way we currently have the logic creates a couple of intermediate arrays just so we can call `forEach` at the end.
These changes use a regular `for` loop with an `if` statement instead. This isn't a _massive_ performance improvement, but the logic does run during app initialization which is performance-sensitive and it's an easy change to make on our end.

Class static properties with initializers that cause code execution (for example, call expressions or new expressions) have the potential to cause side effects at module evaluation. This is similar in effect to module level code. As a result, optimizers can not safely remove a class with such a static property as the potential side effects may have meaningful effects on the state of the application execution. To allow classes with these type of static properties to be optimized and removed if unused, the initializer expressions for the static properties can be annotated as pure. This annotation provides a signal to an optimizer that the expression does not have any potential side effects and is useful in cases where static analysis can not currently prove that there are, in fact, no side effects caused by the initializer.

The previously used code (`<live-example stackblitz="router">`) would
try to target the `router.stackblitz.json` file inside the
(non-existent) `routing-overview` example (same as the guide's name).
This commit fixes the code to correctly express the original intention
of targeting the default `stackblitz.json` file of the `router` example
with `<live-example name="router">`.
