Use option --jmods-dir NO_JMODS for Mandrel based on JDK 24

[jerboaa]

This change is contingent on two dependency PRs:

• mx: Enable build support for JEP 493 enabled base JDKs mx#287
• oracle/graal: [GR-60173] Register custom module-info compilation participant for JDK builds without JMODs oracle/graal#10161

Closes: graalvm/mandrel#808

[jerboaa]

CI currently fails due to NO_JMODS not being appropriately interpreted. I'll only integrate once all the deps are in place.

[jerboaa]

Re-running all jobs now that dependent PRs are in. Lets see how that goes.

[jerboaa]

Hmm, something is still not quite right. Investigating...

[jerboaa]

OK, CI used 645d27a7cf8953a5a2904c0e726ba3630be85fd8 which doesn't have oracle/graal@7d964fa. I'll manually sync graal/master and will try again.

Sync job: https://github.com/graalvm/mandrel/actions/runs/12130475478 which brought it up to upstream master tip which currently is 36c69edf65ee12a5e43b721c7f4813419c279b63. The re-triggered jobs should now work (provided JDK 24+26 EA builds are OK; I've tested with JDK 24+25).

OK failure is now due to a missing JVM CI update to bump to 24+26 as it fails at native image agent generation:

The 2-step build builds the jars fine:

INFO [build] Congratulations you successfully built Mandrel 10.9.8.7-dev based on Java 24-beta+26-ea

The native bits is what's failing. @zakkak Could you please review this so that we can get past graalvm/mandrel#808, thanks!

[zakkak]

LGTM thanks @jerboaa!

Regarding the 24+26 related failures oracle/graal#10216 should fix them.

[jerboaa]

Thanks!
