fix: add module opens for all selected test classes

[wenytang-ms]

Summary

• pass JDT handles for multi-class JUnit launches
• let the upstream JDT delegate evaluate the exact selected types so it generates --add-opens for every package
• preserve the fast single-main-type launch setup and add a modular multi-package regression test

Testing

• npm test
• mvn -f java-extension\pom.xml -pl com.microsoft.java.test.target,com.microsoft.java.test.plugin,com.microsoft.java.test.plugin.test -am verify

Fixes #1883

Pull request overview

This PR addresses JPMS modular-project failures in multi-class JUnit launches by ensuring the upstream JDT delegate can evaluate the full selected test set (not just the first “main type”), so it generates complete --add-opens VM arguments for all involved packages.

Changes:

• Pass JDT handle identifiers for multi-class (class-level) JUnit selections from the TypeScript client to the Java extension.
• Override JDT’s evaluateTests to resolve all selected ITypes from handles before VM args are computed, enabling complete --add-opens generation.
• Add a regression test project + test case covering multi-package modular JUnit selection behavior.
