  [flang][cuda] Add conversion pass for cuf.allocate and cuf.deallocate (#101563)

Allocator can be specified in the descriptor. For simple local
allocatable, we can simply convert `cuf.allocate`/`cuf.deallocate` to
their corresponding runtime calls in the standard flang runtime. More
specific cases will require dedicated entry points. Global descriptor
will require sync between host and device copy.

This patch adds a pass to perform this conversion.
