Add support for Surround with TryCatch for Runtime Exceptions

[gayanper]

Take the following code example and try to invoke Surround with Snippet, I would expect try catch snippet which will allow me to select the Exception types provided by jdt.ls which are thrown by the foo() method according to jdt.ls completion rules.

public class App {

  public void foo() throws IllegalStateException {
  }

  public static void main(String[] args) {
     foo();
  }
