Fix retry logic for unit test (#7471)

* Fix the ignored unit-tests on retry

* Retrigger CI

* Add more error messages

* Don't use test-server for retry of unit-test to see error messages

* Clean up cl.yml

Remove 'has-gpu' because it is unused after debug became full-gpu-test.
Renamed files to make the meaning more clear:
- Renamed expected-failure.txt to expected-failure-via-glsl.txt
- Renamed expected-failure-github-runner.txt to expected-failure-no-gpu.txt

* Rename cpu-hello-world.slang to avoid name conflict to example

We have an example whose executable name is cpu-hello-world.exe.
It gets built when you run `cmake --build`, but it gets overwritten by
slang-test when it tests `tests/cpu-program/cpu-hello-world.slang`.

This PR renames to avoid the name conflict.

* Remove debug code
