  [flang][cuda] Support data transfer from pointer to a descriptor (#114892)

When source is a pointer to an array or a scalar, embox it and use the
`CUFDataTransferDescDesc` or `CUFDataTransferGlobalDescDesc` entry
points. The runtime is already able to deal with all the corner cases
like non contiguous arrays and so on so we exploit this.

Memset might still be used for simple case where we want to initialize
to 0 for example. This will come in a follow up patch.
