Provide an enum class used to distinguish among various memory types. This allows decoupling of the concept of memory type from a specific mdspan accessor policy and ensures that templates receive only a logically-consistent memory type.
As a follow-up to rapidsai#984 which introduces a memory_type enum, this PR introduces a device_type enum with similar justifications.

As a follow-up to #984 which introduces a memory_type enum, this PR introduces a device_type enum with similar justifications.
