  [flang][cuda] Support data transfer from descriptor to a pointer (#115023)

Data transfer from a variable with a descriptor to a pointer. We create
a descriptor for the pointer so we can use the flang runtime to perform
the transfer. The Assign function handles all corner cases. We add a new
entry points `CUFDataTransferDescDescNoRealloc` to avoid reallocation
since the variable on the LHS is not an allocatable.
