Merge `parseList` and `parseListCmp` into one generic function

This issue merges `parseList` and `parseListCmp` functions into one generic function.

• As-Is
  Utils.java

    /**
     * TODO: Merge with parseListCmp() into one generic implementation.
     */
    public static List<Identifier> parseList(
        final String ids, final IdentifierFactory factory) {
      final List<Identifier> result = new ArrayList<>();
      for (final String token : ids.split(DELIMITER)) {
        result.add(factory.getNewInstance(token.trim()));
      }
      return result;
    }
  
    /**
     * TODO: Merge with parseList() into one generic implementation.
     */
    public static List<ComparableIdentifier> parseListCmp(
        final String ids, final IdentifierFactory factory) {
      final List<ComparableIdentifier> result = new ArrayList<>();
      for (final String token : ids.split(DELIMITER)) {
        result.add((ComparableIdentifier) factory.getNewInstance(token.trim()));
      }
      return result;
    }
  

• To-Be
  Utils.java

  public static <T extends Identifier> List<T> parseList(final String ids, final IdentifierFactory factory) {
      final List<T> result = new ArrayList<>();
      for (final String token : ids.split(DELIMITER)) {
        result.add((T) factory.getNewInstance(token.trim()));
