This adds initial support for ReBAR capable platforms.
It ensures that when allocating buffers that should not be host visible, still
tries to allocate in host visible memory. When there is space in this memory
heap the buffer will be automatically mapped to host memory.
When mapped staging buffers can be skipped when the buffer was newly
created. In order to make better usage of ReBAR the `VKBuffer::create`
function will need to be revisit. It currently hides to much options to allocate
in the correct memory heap. This change isn't part of this PR.
Using shader_balls.blend rendering the first 50 frames in main takes 1516ms.
When using ReBAR it takes 1416ms.
