Dyno: promote methods

[DanilaFe]

Closes https://github.com/Cray/chapel-private/issues/7401.

Specifically, this PR properly handles calls to methods that are the scalar type" of another type. E.g., this makes it possible to invoke a method on each element of an array or records/classes. Sample code from #7401:

record R {
  proc helper() {
    return 5;
  }
}

proc main() {
  var A : [1..10] R;
  var B = A.helper();
}

Testing

• dyno tests
• code in cray/chapel-private#7401 works
• types/atomic/sungeun/atomic_vars compiles with --dyno-resolve-only -comp-only
• paratest --dyno-resolve-only
• paratest
