  [flang] Preserve bound info for pointer assignments through derived types

Doing a pointer assignment to another pointer which is a derived type component
could result in the bound information being lost, potentially leading to
incorrect array accesses. Fix this by trying to retain the bound info during
the assignment.

Fixes #57441
