Previously, the i18n message extractor just quietly ignored messages that
it extracted that had the same id. It can be helpful to identify these
to track down messages that have the same id but different message text.
Now the messages are checked for duplicate ids with different message text.
Any that are found can be reported based on the new `--duplicateMessageHandling`
command line option (or `duplicateMessageHandling` API options property).
* "ignore" - no action is taken
* "warning" - a diagnostic warning is written to the logger
* "error" - the extractor throws an error and exits

Currently the Ivy language service bundle is [10MB](
https://unpkg.com/browse/@angular/[email protected]/bundles/) because we
accidentally included typescript in the bundle.
With this change, the bundle size goes down to 1.6MB, which is even smaller
than the View Engine bundle (1.8MB).
```bash
$ yarn bazel build //packages/language-service/bundles:ivy
$ ls -lh dist/bin/packages/language-service/bundles/ivy.umd.js
1.6M Jul 15 15:49 dist/bin/packages/language-service/bundles/ivy.umd.js

`ls_rollup_bundle` is no longer needed since we could invoke `ng_rollup_bundle`
directly.
Background: language service runs rollup to produce a single file to reduce
startup time in the editor. However, due to the need to load dynamic versions
of typescript at runtime (think the case where users can change typescript
version in their editor), we hack the "banner" to export a CommonJS default function,
so that we could dynamically load the typescript module provided at runtime via AMD
and use it throughout the implementation.

Currently we read lifecycle hooks eagerly during `ɵɵdefineComponent`.
The result is that it is not possible to do any sort of meta-programing
such as mixins or adding lifecycle hooks using custom decorators since
any such code executes after `ɵɵdefineComponent` has extracted the
lifecycle hooks from the prototype. Additionally the behavior is
inconsistent between AOT and JIT mode. In JIT mode overriding lifecycle
hooks is possible because the whole `ɵɵdefineComponent` is placed in
getter which is executed lazily. This is because JIT mode must compile a
template which can be specified as `templateURL` and those we are
waiting for its resolution.
- `+` `ɵɵdefineComponent` becomes smaller as it no longer needs to copy
lifecycle hooks from prototype to `ComponentDef`
- `-` `ɵɵNgOnChangesFeature` feature is now always included with the
codebase as it is no longer tree shakable.
Previously we have read lifecycle hooks from prototype in the
`ɵɵdefineComponent` so that lifecycle hook access would be monomorphic.
This decision was made before we had `T*` data structures. By not
reading the lifecycle hooks we are moving the megamorhic read form
`ɵɵdefineComponent` to instructions. However, the reads happen on
`firstTemplatePass` only and are subsequently cached in the `T*` data
structures. The result is that the overall performance should be same
(or slightly better as the intermediate `ComponentDef` has been
removed.)
- [ ] Remove `ɵɵNgOnChangesFeature` from compiler. (It will no longer
be a feature.)
- [ ] Discuss the future of `Features` as they hinder meta-programing.

Fixes the following issues related to how we validate properties during JIT:
- The invalid property warning was printing `null` as the node name
for `ng-content`. The problem is that when generating a template from
`ng-content` we weren't capturing the node name.
- We weren't running property validation on `ng-container` at all.
This used to be supported on ViewEngine and seems like an oversight.
In the process of making these changes, I found and cleaned up a
few places where we were passing in `LView` unnecessarily.

The function was removed by default in Bazel 0.27.
It is still accessible with the flag `--incompatible_new_actions_api`
(which is set in Google code base), but the flag will be deleted very soon.
This change should be a no-op for Bazel users. The change was tested in
Google (cl/318277076) and should be safe as well.

Adds Firefox as browser to `dev-infra/browsers` with RBE
compatibility. The default Firefox browser is not compatible similar to
the default Chromium version exposed by `rules_webtesting`.
The Angular Components repository will use this browser target as
it enables RBE support. Also it gives us more flexibility about
the Firefox version we test against. The version provided by
`rules_webtesting` is very old and most likely not frequently
updated (based on past experience).

In CLI v10 there was a move to use the new solution-style tsconfig
which became available in TS 3.9.
The result of this is that the standard tsconfig.json no longer contains
important information such as "paths" mappings, which ngcc might need to
correctly compute dependencies.
ngcc (and ngc and tsc) infer the path to tsconfig.json if not given an
explicit tsconfig file-path. But now that means it infers the solution
tsconfig rather than one that contains the useful information it used to
get.
This commit logs a warning in this case to inform the developer
that they might not have meant to load this tsconfig and offer
alternative options.
