8342988: GHA: Build JTReg in single step

[shipilev]

Makes sure GHA is more reliable: we do not risk failures when building jtreg multiple times, and it also allows us to compile it once on x86, without bothering with different arch JDKs.

The original PR does not apply cleanly, because Alpine support added by JDK-8282944 is not in JDK 21. I have resolved the block by hand.

Additional testing:

• GHA

Progress

• Change must be properly reviewed (1 review required, with at least 1 Reviewer)

⚠️ @shipilev This change is now ready for you to apply for maintainer approval. This can be done directly in each associated issue or by using the /approval command.

/approval request Makes sure GHA is more reliable: we do not risk failures when building jtreg multiple times, and it also allows us to compile it once on x86, without bothering with different arch JDKs. Does not apply cleanly, because Alpine changes are missing in 21u. Otherwise clean, GHA tests pass. Risk is low, GHA-only change.

It would be great if this reduces the wget failures!!!

Right? :) In mainline, the failures are still happening occasionally, but at least they fail in the first minute, so you can restart the testing right away.
