The decorator downlevel transform is never used for actual class
decorators because Angular class decorators rely on immediate execution
for JIT. Initially we also supported downleveling of class decorators
for View Engine library output, but libraries are shipped using partial
compilation output and are not using this transform anymore.
The transform is exclusively used for JIT processing, commonly for
test files to help ease temporal dead-zone/forward-ref issues. We can
remove the class decorator downlevel logic to remove technical debt.

ZoneJS is no longer loaded as an UMD, but instead is included as part
of the browser init entry-point. This means that ZoneJS is bundled and
the ESBuild logic needs to be adjusted for that.

Previously with ESBuild 0.14.11, when a file had dynamic requires to
builtin NodeJS modules like `url`, the resolution completed successfully
regardless of `--platform browser`. This seems to be fixed in ESBuild now.
This unveiled some resolution errors with our Saucelabs bundle generation
because the framework code sometimes switches dynamically to `require('url')`
if `window.URL` is not defined. Previously this just didn't matter, but now
the `require('url')` is checked and a module resolution error is reported given
`url` not being available in the browser as a builtin module.
We fix this by marking the module as external. We will not hit this code path
anyway in the browser saucelabs code. Similarly we exclude all platform-server
files from the bundle. This is not strictly needed after the `url` module being
marked as external, but the issue showed that lots of unnecessary code for the
server platform is included. This can be omitted (unfortunately not from the TS
compilation without over-complicating things significantly more; experimented with
that).

Fixes lint errors in the build-saucelabs legacy script. Likely this only
surfaces now after merge due to some other lint-affecting changes
landing just before the script landed.

Previously, when we did not bundle tests, we also had the jasmine
default timeout increased to 15000ms. This commit re-introduces this
increased timeout by also maintaining a custom test init file for the
legacy saucelab jobs. This is desirable as all of the Saucelabs test
code is local in the `tools/legacy-saucelabs` folder.

Bundle spec files similar to how it is done within the Angular
Components repo. This should simplify the setup and also speed
up the Saucelab job as only a single spec bundle would need to be
downloaded, compared to having to load hundreds of files through the
Saucelabs tunnel.
Also makes a couple of tests more robust with the emulators/and accounts
for ES2015 test runner changes. The tests should be less reluctant to
such build process changes.
Note for reviewers: Some imports have been simplified here. This work
came from Joey's original WIP for this. It's unclear to me whether this
is still needed, but it sounded like this was necessary for the ESBuild
bundling to work. I have robusted the module resolution plugin though,
so I doubt it's still needed. At the same time though: Not worth
reverting/trying as these changes are nice to have anyway!
