[fix](ci) Fix BE UT macOS workflow for ARM64 runner

The macos-15 runner uses ARM64 (Apple Silicon), but the workflow was
configured for x86_64, causing JDK version detection to fail with
'ERROR: The JAVA version is 25, it must be JDK-17'.

Changes:
- Use JAVA_HOME_17_ARM64 instead of JAVA_HOME_17_X64
- Download darwin-arm64 thirdparty prebuilt instead of darwin-x86_64
- Install openjdk@17 instead of openjdk@11 via brew
