Enable method overloading and overriding

[AprupKale]

Enable running multiple classes in java-slang.

Enable method overloading and overriding to support code as follows:

public class Main {
  public void f(int x) {
    System.out.println("Instance int: " + x);
  }
  public void f(double x) {
    System.out.println("Instance double: " + x);
  }
  public static void main(String[] args) {
    Main obj = new Main();
    obj.f(5);
    obj.f(5.5);
  }
}

and

class Parent {
  public static void staticMethod() {
    System.out.println("Parent static method");
  }
  public void instanceMethod() {
    System.out.println("Parent instance method");
  }
}

class Child extends Parent {
  public static void staticMethod() {
    System.out.println("Child static method");
  }
  public void instanceMethod() {
    System.out.println("Child instance method");
  }
}

public class Main {
  public static void main(String[] args) {
    Parent.staticMethod(); // Parent static method
    Child.staticMethod(); // Child static method
    Parent ref = new Child();
    ref.instanceMethod(); // Child instance method
  }
}

Code Review

This pull request implements support for SwitchStatement and CastExpression, covering grammar updates, AST extraction, type checking, and bytecode generation. It also enhances method invocation to support overloading, overriding, and super calls, and enables the compiler to handle multiple class files. Feedback highlights several critical issues, including incorrect usage of the in operator and filter method in TypeScript, flawed JVM offset patching for switch instructions, and a missing string collision check in switch statements. Additionally, the reviewer identified logic errors in the final method override checks and inconsistent package naming conventions that could lead to lookup failures.
