  Fix 10619 - Wrong local variable passed as alias arguments to templates

  PR #12119 introduced `localNum` to differentiate between multiple
  symbols with identical names. But `Dsymbol.equals` doesn't consider
  this variable when comparing two Dsymbols.

  This caused template semantic to treat the second instantiation of
  `foo` as a duplice in the following example:

  ```d
  void main()
  {
      {
          int x = 1;
          foo!x();
      }
      {
          int x = 2;
          foo!x();
      }
  }
  ```
