  [flang] implement assumed-rank in ENTRY (#96111)

With `createUnallocatedBox` utility change from #96106 , the TODO for assumed-rank in entry
can simply be lifted and test is added.

The key is that a unallocated assumed-rank descriptor is created with
rank zero in the entry where an assumed-rank dummy from some other entry
do not appear as a dummy (the symbol must still be mapped to some valid
value because the symbol could be used in code that would be unreachable
at runtime, but that the compiler must still generate).
