And add the same to buffer_kernel.hpp in the !IS_BSP clause.

Description
This change updates
zero_copy_kernelsample on how the buffer locations are being selected in the sample to match the new 2024.0 IPA interfaces definitions.In
zero_copy_kernelboth accessor (requiring device allcoated memory) and USM host pointer are used. In full-system flow, the board spec has defined a device global memory and a host/shared global memory. While in IP-Authoring flow,buffer_locationshould be specified onaccessorandannotated_argso the compiler can infer global memory interfaces and generate board spec.Type of change
