  -----------
  [flang][cuda] Allocate the dst descriptor in data transfer (#143437)

In a test like: 

```
integer, allocatable, device :: da(:)
allocate(a(200))
a = 2
da = a ! da is not allocated before data transfer is initiated. Allocate it with a
```

The reference compiler will allocate the data for the `da` descriptor so
the data transfer can be done properly.
