8342988: GHA: Build JTReg in single step

[vieiro]

Backport of JDK-8349829 from 17u to build jtreg and cache it for subsequent builds. Low risk (only GHA actions affected).

The backport is not clean as JDK-8338286 has not been backported to JDK-11, on purpose. Also JAVA_HOME_11_X64 is being used now to build jtreg.

As expected jtreg is now being built & cached in subsequent builds:

2025-02-14T17:08:58.7115863Z Cache restored successfully
2025-02-14T17:08:58.7298813Z Cache restored from key: jtreg-7.3.1+1

All tests pass but I detected an intermittent time- out in serviceability agent in macos (possibly because of JDK-8260389? despite JDK-8294316 having been already integrated. This is under investigation).

There seems to be a problem of still building JTREG if it's not found in the cache in actions/get-jreg/action.yml. Instead, we should not look in the cache but use download-artifact as is being done on the JDK 17 version of this. Am I missing something?

[jerboaa]

This still builds jtreg? Shouldn't it use actions/download-artifact@v4 to get the built version like is done on the JDK 17 version of this patch:
