Is your feature request related to a problem? Please describe.

The <memory> header provides a lot of useful machinery that handles the non so subtle topic of memory allocation and handling of uninitialized memory.

To improve user experience we should implement this within libcu++ and also provide extensions that leverage e.g different memory categories that we have on device.

this depends on both #179 and #180

Describe the solution you'd like

We should continue our modularization efforts here and see what extensions are suitable

Describe alternatives you've considered
