Remove TypeScript 3.6 and 3.7 support from Angular along with tests that
ensure those TS versions work.
BREAKING CHANGE: typescript 3.6 and 3.7 are no longer supported, please
update to typescript 3.8

* it's tricky to get out of the runfiles tree with `bazel test` as `BUILD_WORKSPACE_DIRECTORY` is not set but I employed a trick to read the `DO_NOT_BUILD_HERE` file that is one level up from `execroot` and that contains the workspace directory. This is experimental and if `bazel test //:test.debug` fails than `bazel run` is still guaranteed to work as `BUILD_WORKSPACE_DIRECTORY` will be set in that context
* test //integration:bazel_test and //integration:bazel-schematics_test exclusively
* run "exclusive" and "manual" bazel-in-bazel integration tests in their own CI job as they take 8m+ to execute
```
//integration:bazel-schematics_test PASSED in 317.2s
//integration:bazel_test PASSED in 167.8s
```
* Skip all integration tests that are now handled by angular_integration_test except the tests that are tracked for payload size; these are:
- cli-hello-world*
- hello_world__closure
* add & pin @babel deps as newer versions of babel break //packages/localize/src/tools/test:test
@babel/core dep had to be pinned to 7.6.4 or else //packages/localize/src/tools/test:test failed. Also //packages/localize uses @babel/generator, @babel/template, @babel/traverse & @babel/types so these deps were added to package.json as they were not being hoisted anymore from @babel/core transitive.
NB: integration/hello_world__systemjs_umd test must run with systemjs 0.20.0
NB: systemjs must be at 0.18.10 for legacy saucelabs job to pass
NB: With Bazel 2.0, the glob for the files to test `"integration/bazel/**"` is empty if integation/bazel is in .bazelignore. This glob worked under these conditions with 1.1.0. I did not bother testing with 1.2.x as not having integration/bazel in .bazelignore is correct.

skipLibCheck=false is currently the default (in tsc 3.7.4) but it wouldn't be shocking if the default
changed in the future because skipLibCheck=true makes more sense in almost all scenarios. So just to be
defensive and explicit, I'm setting the flag to false even though it's the current default.

In the `integration_test` CircleCI job, we run `yarn install` on all
projects in the `integration/` directory. If a project has no lockfile
or if the lockfile is out-of-sync with the corresponding `package.json`
file, then the installed dependency versions are no longer pinned, which
can result in different versions being installed between different runs
of the same job (if, for example, a new version is released for a
package) and breaks hermeticity.
This could be prevented by using the `--frozen-lockfile` option with
`yarn install`, but this is not possible with the current setup, because
yarn needs to be able to install the locally built Angular packages,
whose checksums will be different from the ones in the lockfile.
Therefore, we have to manually ensure that the lockfiles remain in-sync
with the corresponding `package.json` files for the rest of the
dependencies.
For example, previously, [cli-hello-world-lazy/yarn.lock][1] had an
entry for `@angular-devkit/build-angular@0.900.0-next.9` (pinned to
`0.900.0-next.9`), but [cli-hello-world-lazy/package.json][2] specified
the `@angular-devkit/build-angular` version as `^0.900.0-rc.0` (note the
leading caret). As a result, since the version in the lock file does not
much the one in `package.json`, the lockfile is ignored and the latest
available version that matches `^0.900.0-rc.0` is installed.
This, for example, started causing unrelated CI failures ([example][3]),
when `@angular-devkit/build-angular@9.0.0-rc.3` was released with a size
improvement.
This commit ensures that all integration projects have a lockfile and
that lockfiles are up-to-date (with the current `package.json` files).

In #33046, internal uses of `zone.js` were switched to reference it
directly from source (built with Bazel) instead of npm. As a result, the
necessary scripts were updated to build `zone.js` as necessary. However,
some `integration/**/debug-test.sh` scripts were missed (apparently
because they are not used on CI, but only locally as helpers for
debugging the integration projects).
This commit updates the `scripts/build-packages-dist.sh` script to also
build `zone.js`, so that other scripts (such as the various
`debug-test.sh` scripts) can use it.
