  -----------
  [flang][runtime] Preserve type when remapping monomorphic pointers (#149427)

Pointer remappings unconditionally update the element byte size and
derived type of the pointer's descriptor. This is okay when the pointer
is polymorphic, but not when a pointer is associated with an extended
type.

To communicate this monomorphic case to the runtime, add a new entry
point so as to not break forward binary compatibility.
