Prior to this commit, we had two different modes for change detection
execution for Ivy, depending on whether you called `bootstrap()` or
`renderComponent()`. In the former case, we would complete creation
mode for all components in the tree before beginning update mode for
any component. In the latter case, we would run creation mode and
update mode together for each component individually.
Maintaining code to support these two different execution orders was
unnecessarily complex, so this commit aligns the two bootstrapping
mechanisms to execute in the same order. Now creation mode always
runs for all components before update mode begins.
This change also simplifies our rendering logic so that we use
`LView` flags as the source of truth for rendering mode instead of
`rf` function arguments. This fixed some related bugs (e.g. calling
`ViewRef.detectChanges` synchronously after the view's creation
would create view nodes twice, view queries would execute twice, etc).

BREAKING CHANGE:
The public API for `DebugNode` was accidentally too broad. This change removes
1. Public constructor. Since `DebugNode` is a way for Angular to communicate information
on to the developer there is no reason why the developer should ever need to
Instantiate the `DebugNode`
2. We are also removing `removeChild`, `addChild`, `insertBefore`, and `insertChildAfter`.
All of these methods are used by Angular to constructor the correct `DebugNode` tree.
There is no reason why the developer should ever be constructing a `DebugNode` tree
And these methods should have never been made public.
3. All properties have been change to `readonly` since `DebugNode` is used by Angular
to communicate to developer and there is no reason why these APIs should be writable.
While technically breaking change we don’t expect anyone to be effected by this change.

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

This fix is for the issue below when compiling I18N Angular apps using closure.
For certain locales closure converts the input locale id to a different equivalent locale string. For example if the input locale is 'id'(for Indonesia) goog.LOCALE is set to 'in' and the closure locale data is registered only for 'in'. The Angular compiler uses the original input locale string, 'id' to set the LOCALE_ID token and there is a mismatch of locale used to register and locale used when requesting the locale data.
The fix is for the closure-locale.ts code to register the locale data for all equivalent locales names so that it doesn't matter what goog.LOCALE is actually set to.

With these changes, the types are a little stricter now and also not

This lets projects like Material change ng_package "bundle index" files to non-conflicting paths
Currently packages like @angular/core ship with the generated metadata
in a path like 'core.js' which overwrites one of the inputs.
Angular material puts the generated file in a path like 'index.js'
Either way these files generated by ng_module rules have the potential
to collide with inputs given by the user, which results in an error.
Instead, give users the freedom to choose a different non-conflicting name.
Also this refactors the ng_package rule, removing the redundant
secondary_entry_points attribute.
Instead, we assume that any ng_module in the deps with a module_name
attribute is a secondary entry point.

"ng update" supports having multiple packages as part of a group which should be updated together, meaning that e.g. calling "ng update @angular/core" would be equivalent to updating all packages of the group (that are part of the package.json already).
In order to support the grouping feature, the package.json of the version the user is updating to needs to include an "ng-update" key that points to this metadata.

Previously, an interceptor attempting to inject HttpClient directly
would receive a circular dependency error, as HttpClient was
constructed via a factory which injected the interceptor instances.
Users want to inject HttpClient into interceptors to make supporting
requests (ex: to retrieve an authentication token). Currently this is
only possible by injecting the Injector and using it to resolve
HttpClient at request time.
Either HttpClient or the user has to deal specially with the circular
dependency. This change moves that responsibility into HttpClient
itself. By utilizing a new class HttpInterceptingHandler which lazily
loads the set of interceptors at request time, it's possible to inject
HttpClient directly into interceptors as construction of HttpClient no
longer requires the interceptor chain to be constructed.

Allows a directive to use the expression passed directly to a property

Closure Compiler cannot infer that the swtich statement is exhaustive,
which causes it to complain that the method does not always return a
value.
Work around the problem by throwing an exception in the default case,
and using the `: never` type to ensure the code is unreachable.
Structural directives can now specify a type guard that describes
what types can be inferred for an input expression inside the
directive's template.
NgIf was modified to declare an input guard on ngIf.
After this change, `fullTemplateTypeCheck` will infer that
usage of `ngIf` expression inside it's template is truthy.
For example, if a component has a property `person?: Person`
and a template of `<div *ngIf="person"> {{person.name}} </div>`
the compiler will no longer report that `person` might be null or
undefined.
The template compiler will generate code similar to,
```
if (NgIf.ngIfTypeGuard(instance.person)) {
instance.person.name
}
```
to validate the template's use of the interpolation expression.
Calling the type guard in this fashion allows TypeScript to infer
that `person` is non-null.

Currently HttpClient sends requests for JSON data with the
XMLHttpRequest.responseType set to 'json'. With this flag, the browser
will attempt to parse the response as JSON, but will return 'null' on
any errors. If the JSON response contains an XSSI-prevention prefix,
this will cause the browser's parsing to fail, which is unrecoverable.
The only compelling reason to use the responseType 'json' is for
performance (especially if the browser offloads JSON parsing to a
separate thread). I'm not aware of any browser which does this currently,
nor of any plans to do so. JSON.parse and responseType 'json' both
end up using the same V8 code path in Chrome to implement the parse.
Thus, this change switches all JSON parsing in HttpClient to use
JSON.parse directly.

Today, constructing a new GET request with headers looks like:
const headers = new HttpHeaders({

This indirection is unnecessary. It'd be more ergonomic to write:
http.get('/url', {headers: {'My-Header': 'header value'}}).subscribe(...);
This commit allows that new syntax, both for HttpHeaders and HttpParams.
