ci: stop running the macOS build under Rosetta

macos-latest is now macos-26-arm64, but setup-java pinned
architecture: x64, so the runner fetched an x86_64 Zulu JDK and every
JVM in the build -- Maven, each Surefire fork, the Kotlin daemon -- ran
under Rosetta 2 emulation. The Maven step took 52m29s on macOS against
18m45s on Ubuntu, a uniform 2-6x penalty across every module rather
than one slow test. The GraalVM jobs in the same workflow pin no
architecture, get a native arm64 JDK, and finish a full clean install
in three minutes.

Drop the pin from all three jobs. Ubuntu and Windows runners are x64
anyway, so it is a no-op there and removes the same trap when those
images move to arm.

Also drop JAVA_OPTS. Maven reads MAVEN_OPTS and no argLine forwards it,
so those flags never reached any JVM on any OS -- the Kotlin daemon
launches without them in the logs. Dead config, and a pessimization
(C1-only JIT) had it ever applied.
