Fixed compile errors for IsHipDevicePointer

This function was trying to reference a member named TYPE_ATTR in the hipPointerAttribute_t. This member does not exist.

The intention of TYPE_ATTR was probably a macro that selected the name memoryType for HIP 5 and earlier and type for HIP 6 and later. Since Viskores currently only supports HIP 6 and up, the code now just uses type.

The device pointer check also now includes hipMemoryTypeManaged. The documentation is not clear what the difference between this and hipMemoryTypeUnified is. Presumably it comes from these identifiers being a mashup of identifiers from multiple CUDA enums.
