infra: Define custom mega CQ run modes & enable it on mega cq builder

Now that crbug.com/1483511 is fixed and we're out of the freeze, we
should finally be able to hook-up the mega cq button in gerrit to an
actual cq attempt.

So this defines the two custom run_modes for the mega CQ & configures
the mega-cq-launcher builder to be triggered by that run mode.

The launcher will handle triggering sub-builds of real builders, so
we don't need to list any other builder on these run modes for now.
If/when we delete the launcher and use native CV functionality for the
mega CQ, then we'd need to allowlist all relevant builders. ie:
This TODO:
https://source.chromium.org/chromium/chromium/src/+/main:infra/config/lib/builder_config.star;drc=dd5ca12dd573a863573e83f30486e7638aa43c60;l=793

But that's blocked on crbug.com/1483516.
