Currently the Ivy language service bundle is [10MB](
https://unpkg.com/browse/@angular/language-service@10.0.4/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

`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.

In #37957, parts of the testing guide were broken out into separate
guides. As part of that work, the `<live-example>` tags were also copied
to the new guides. These `<live-example>` tags did not specify the
targeted example project via the `name` attribute, thus they were
implicitly targeting the example with the same name as the guide they
were in. See the [Docs style guide][1] for more info.
However, there is only one example project (`testing/`) and all
`<live-example>` tags were supposed to target that. This worked fine on
the `testing.md` guide, but it broke on other guides (which tried to
target non-existing example projects based on their names).
This commit fixes it by explicitly specifying which example is targeted
by the `<live-example>` tags. It also removes the `embedded-style`
attribute that has no effect.

The current method of handling duplicate navigations caused by 'hashchange' and 'popstate' events for the same url change does not correctly handle cancelled navigations. Because `scheduleNavigation` is called in a `setTimeout` in the location change subscription, the duplicate navigations are not flushed at the same time. This means that if the initial navigation hits a guard that schedules a new navigation, the navigation for the duplicate event will not compare to the correct transition (because we inserted another navigation between the duplicates).

With `rules_nodejs` v2.0.0 being in RC phase currently, we should
make sure that the package is compatible so that we can use it
in the components repo in combination with rules_nodejs v2.0.0.
In v2.0.0 of the NodeJS rules, Bazel workspaces are recommended
to no longer be symlinked under a separate repository. Instead,
bazel rules and targets should be accessed directly from the
user-selected NPM repository. Usually `@npm`, so that the import
changes to `@npm//@angular/dev-infra-private/<..>`.

The `fs.relative()` method assumed that the file-system is a single tree,
which is not the case in Windows, where you can have multiple drives,
e.g. `C:`, `D:` etc.
This commit changes `fs.relative()` so that it no longer forces the result
to be a `PathSegment` and then flows that refactoring through the rest of
the compiler-cli (and ngcc). The main difference is that now, in some cases,
we needed to check whether the result is "rooted", i.e an `AbsoluteFsPath`,
rather than a `PathSegment`, before using it.

This file is inert unless it's explicitly included into the local git config via:
```
git config --add include.path '../.ng-dev/gitconfig'
```
Calling that command will append the following into `.git/config` of the current git workspace
(i.e. $GIT_DIR, typically `angular/.git/config`):
```
[include]
path = ../.ng-dev/gitconfig
```
I'm intentionally keeping the config inert for now until we prove that this is a good idea.
Eventually we could roll this change out to all the contributors via an npm post-install script.
