It is recommended to map buffers once and not each time the mapped memory is needed. This patch will map the buffer when created and unmap the buffer when the buffer is freed. This patch will reduce the overhead where the Vulkan driver or the virtual memory manager needs to be accessed. Pull Request: blender/blender#105588
