Remove linux debug target, and change test results publisher to test-…

…summary/action because it is faster. (youtube#4573)

b/372303096

Change to use a new test publisher because the existing publisher can
take over an hour to run when there are many test failures:
https://github.com/youtube/cobalt/actions/runs/12302321578/job/34336630966?pr=4569

The new publisher reports >2000 failures with annotations in 3 seconds:

https://github.com/youtube/cobalt/actions/runs/12472477285/job/34812061568?pr=4573

Also remove debug from linux build targets because it takes >1 hour to
complete.
