Memory areas was requested to be preferable host visible. On some platforms this would fail to allocate. Best is to not add preferable host visible for typically large allocations. This PR also gives the caller the responsibility to set the allocation flags. Pull Request: https://projects.blender.org/blender/blender/pulls/133528
