ci: Switch cheza (freedreno a630) testing to baremetal.

Now that we have scripts in place to do baremetal testing of cheza, switch
it over.  As of this writing, we have 5 chezas for baremetal and 4 for the
old docker CI setup (just 2 fewer than we originally had before this work,
since some had had filesystem failures and I switched those first), and
once we are sure of this we can backport to stable branch CI and move the
rest of them to baremetal.

I've run a lot of jobs through the baremetal scripts as I worked on
sorting out vulkan CTS stability, so I feel good about the stability of
the GLES CTS here.

The options job is now split out to separate jobs, as we don't currently
have a way to stack multiple sets deqp runs with different env vars in a
single baremetal run, and just chaining cros_servo.sh invocations runs
into a lack of cleanup of the serial-watching scripts which we rely on
container exit sorting out for us.  This means a little less than 2x the
artifacts downloads we had before for a630 and a few more container
instantiations.
