  [flang] Refine checks on assignments to coarrays (#129966)

F'2023 10.2.1.2 paragraph 2 imposes some requirements on the left-hand
sides of assignments when they have coindices, and one was not checked
while another was inaccurately checked. In short, intrinsic assignment
to a coindexed object can't change its type, and neither can it affect
allocatable components.
