Update BytecodeTranslater tests to verify both 1.5 and 1.8 targets (#4274)
Parameterized `BytecodeInstructionIntegrationTest`, `CleanTargetIntegrationTest`, and `ParserTest` to run with both "1.5" and "1.8" target class levels. Added `isSourceVersionSupported` check to skip "1.5" tests on newer JDKs (like Java 21) where `-source 1.5` is unsupported, ensuring tests pass in diverse environments. Updated `vm/pom.xml` to use source/target 1.8 to enable building on Java 21. Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com>
