  [flang][cuda] Apply implicit managed attribute to scalar pointers (#225934)

Under -gpu=mem:managed, allocatables and array pointers already get an
implicit CUDA managed attribute, but scalar data pointers can still be
EntityDetails during FinishSpecificationPart and only become objects in
ConvertToObjectEntity. That left ALLOCATE of a scalar pointer on the
host heap, so present() failed to find it.

Factor the implicit managed/pinned attribution into
ApplyImplicitCUDADataAttr and invoke it from FinishSpecificationPart,
component declarations, and ConvertToObjectEntity. Skip it when
SetCUDADataAttr is applying an explicit attribute.
