build: switch devmode output to es2015 (#44505)
 
To make our test output i.e. devmode output more aligned
with what we produce in the NPM packages, or to be more
aligned with what Angular applications will usually consume,
the devmode output is switched from ES5 to ES2015.

Additionally various tsconfigs (outside of Bazel) have been
updated to match with the other parts of the build. The rules
are:

ES2015 for test configurations, ES2020 for actual code that will
end up being shipped (this includes the IDE-only tsconfigs).

Raw File
yarn.lock.readme.md 
All of our npm dependencies are locked via the `yarn.lock` file for the following reasons:

- our project has lots of dependencies which update at unpredictable times, so it's important that
  we update them explicitly once in a while rather than implicitly when any of us runs `yarn install`
- locked dependencies allow us to reuse yarn cache on CircleCI, significantly speeding up our builds
  (by 5 minutes or more)
- locked dependencies allow us to detect when node_modules folder is out of date after a branch switch
  which allows us to build the project with the correct dependencies every time

Before changing a dependency, do the following:

- make sure you are in sync with `upstream/master`: `git fetch upstream && git rebase upstream/master`
- ensure that your `node_modules` directory is not stale by running `yarn install`


To add a new dependency do the following: `yarn add <packagename> --dev`

To update an existing dependency do the following: run `yarn upgrade <packagename>@<version|latest> --dev`
or `yarn upgrade <packagename> --dev` to update to the latest version that matches version constraint
in `package.json`

To Remove an existing dependency do the following: run `yarn remove <packagename>`


Once you've changed the dependency, commit the changes to `package.json` & `yarn.lock`, and you are done.
