Update ParparVM tests to run against multiple JDKs and targets
This change updates the CI workflow and the test infrastructure to support running integration tests against multiple JDK versions (8, 11, 17, 21, and 25). Changes: - Updated `.github/workflows/parparvm-tests.yml` to install JDKs 8, 11, 17, 21, and 25 and export their paths as environment variables. The main test execution remains on JDK 8. - Created `CompilerHelper` in `vm/tests` to detect available JDKs from environment variables and manage compilation using `ProcessBuilder` instead of the in-process Compiler API. This avoids classpath pollution and supports newer JDKs. - Updated `BytecodeInstructionIntegrationTest` and `CleanTargetIntegrationTest` to use `CompilerHelper` and run parameterized tests across valid permutations of available Compilers and Target Versions (1.5, 1.8, 11, 17, 21, 25). - Added logic to handle `javac` flag changes on JDK 9+ (replacing `-bootclasspath` with `-classpath` or `--patch-module` as appropriate) and to skip invalid permutations. - Updated `vm/pom.xml` to use ASM 9.7 to support newer Java class file versions.
