Fix static array access metadata

[gshaowei6]

Fixes #86

Summary:

• Record array field assignments/accesses for both instance and static array field refs.
• Resolve the underlying AccessField from array refs, including nested array element refs.
• Add regression coverage for static array field assignment/access metadata and existing instance-array behavior.

Verification:

• Docker JDK8 Maven: mvn -Dtest=com.aparapi.internal.model.EntrypointFieldAccessTest test -> BUILD SUCCESS, Tests run: 2, Failures: 0, Errors: 0, Skipped: 0.
• Manual JUnit run with local JDK 23 javac --release 8: EntrypointFieldAccessTest, AccessIntArrayTest, ClassHasStaticFieldAccessTest, StaticFieldStoreTest (8 tests OK).
