fort_dyn_array: Support evaluation of dynamic elements inside arrays.

fort_dyn_array: Support evaluation of dynamic elements inside arrays.

Resolve type of an array's element to be printed in case it is dynamic.
Otherwise we don't use the correct boundaries nor the right location.

Before:
  ptype fivearr(1)
  type = Type five
      Type one
          integer(kind=4) :: ivla(34196784:34196832,34197072:34197120,34197360:34197408)
      End Type one :: tone
  End Type five

After:
  ptype fivearr(1)
  type = Type five
      Type one
          integer(kind=4) :: ivla(2,4,6)
      End Type one :: tone
  End Type five
