  -----------
  [flang][cuda] Add CUF allocator (#101216)

Add allocators for CUDA fortran allocation on the device. 3 allocators
are added for pinned, device and managed/unified memory allocation.
`CUFRegisterAllocator()` is called to register the allocators in the
allocator registry added in #100690.


Since this require CUDA, a cmake option `FLANG_CUF_RUNTIME` is added to
conditionally build these.
