8338286: GHA: Demote x86_32 to hotspot build only

[shipilev]

As planned in JDK-8338285, we are about to deprecate the port for removal. It makes little sense to continue testing the port, and thus block development and integration of new features.

Ahead of that JEP, we can separately decide to disable the x86_32 test jobs in GHA. This effectively demotes x86_32 to any other port that only builds Hotspot and relies on port maintainers to provide the runtime testing. Building hotspot in both release and debug modes still gives us some level of 32-bit cleanliness checks.

This is deliberately separate change, so that Update Releases could decide to demote their x86_32 jobs as well.

This sounds reasonable. The implementation seems correct.

This is great to see! thanks for pushing it through @shipilev. I wonder if it's time for me to reboot my PR about testing Alpine Linux if we're dropping back on the actions usage here: #7771

[shipilev]

Thanks! Any other opinions on this?

[shipilev]

By the powers vested in me as x86_32 maintainer I declare this PR integrateable. :)
