This is needed to better support native ESM modules and avoid the otherwise necessary deep imports like `zone.js/fesm2015/zone-node.js` due to disallowed directory imports.

Switches the integration tests form Puppeteer/webdriver-manager to the
Bazel-managed Chromium/Chromedriver. This is now possible with the new
integration test rule for which we can consult the
`dev-infra/bazel/browsers` toolchain and setup environment variables.
This has been configured already in a previous commit.
This commit also includes some additional small cleanups necessary for
the new integration test rule:
* The `test.sh` scripts have been renamed as they would conflict with
the `test.sh` scripts generated by the integration test rule.
Previously this was not an issue because tests were declared at a
higher-level. As mentioned though this has other downsides and it is
trivial to rename the file.
* Related to the point above, since tests are now declared witin the
actual test folder (for perf e.g.), `package.json` files setting
`"type": "module"` will accidentally cause the `nodejs_test`-generated
files to be considered ESM. This is not correct and likely needs to be
fixed upstream in `rules_nodejs` where explicit `.cjs` extensions
should be used. This is only happening **once** in the `injectable-def`
test so it is acceptable doing that for now.

Basic integration tests are those which do not require significant
changes as others. The larger ones will have individual commits.
For v13, the NPM package output will always be using partial compilation
output. This makes the ngcc integration test fail because the actual
Angular framework packages are no longer processable. We fix this, and
keep the ngcc test coverage by relying on the v12.x framework packages
in the integration test.
The terser integration test needs to point to the new Flat ESM module
file location. We now output FESM2020 instead of FESM2015. This also
requires us to use the latest version of terser.
The `side-effects` test currently is not maintained by us and relies
on View Engine build output. In the partial compilation output the
partial declarations are not marked with `@PURE` and are not removed
therefore. We would need to update the side-effect test to use the
linker Babel plugin instead. This is currently out-of-scope though
so we disable the test for now.

Rename @Injectable({scope -> providedIn}).
Instead of {providedIn: APP_ROOT_SCOPE}, accept {providedIn: 'root'}.
Also, {providedIn: null} implies the injectable should not be added
to any scope.

This commit bundles 3 important changes, with the goal of enabling tree-shaking
of services which are never injected. Ordinarily, this tree-shaking is prevented
by the existence of a hard dependency on the service by the module in which it
is declared.
Firstly, @Injectable() is modified to accept a 'scope' parameter, which points
to an @NgModule(). This reverses the dependency edge, permitting the module to
not depend on the service which it "provides".
Secondly, the runtime is modified to understand the new relationship created
above. When a module receives a request to inject a token, and cannot find that
token in its list of providers, it will then look at the token for a special
ngInjectableDef field which indicates which module the token is scoped to. If
that module happens to be in the injector, it will behave as if the token
itself was in the injector to begin with.
Thirdly, the compiler is modified to read the @Injectable() metadata and to
generate the special ngInjectableDef field as part of TS compilation, using the
PartialModules system.
Additionally, this commit adds several unit and integration tests of various
flavors to test this change.
