Reorganize chromium.fyi for autogeneration.

The following changes were made:
 - On "Android VR Tests":
   - Alphabetize step names by name, when test was identical.
   - Add a missing "merge" script from one step.
 - On a few bots, remove useless swarming parameters when
   "can_use_on_swarming_builders" was false.
 - Made telemetry_unittests run serially, as on other waterfalls.
 - Alphabetized step names on "Site Isolation Android".

With these changes, this waterfall's JSON can be autogenerated with
100% fidelity.
