RFR: 8341424: GHA: Collect hs_errs from build time failures [v4]

[Aleksey Shipilev]

> GHA conveniently collects hs_errs from the test job runs. However, when we have a failure during the build, e.g. javac, CDS, jmod, jlink crashes the VM, we don't have these automatically collected. This is annoying when VM crashes on a particular platform, and not on others.
> 
> We can add the hooks for these as well. This PR adapts what we already have for test result collectors here: https://github.com/openjdk/jdk/blob/master/.github/scripts/gen-test-results.sh
> 
> I added a deliberate failure point in CDS to demonstrate how it would look like in test summary.
