Currently all buffer types were stored in host memory, which is visible to the GPU as well. This is typically slow as the data would be transferred over the PCI bus when used. Most of the time Index and Vertex buffers are written once and read many times so it makes more sense to locate them on the GPU. Storage buffers typically require quick access as they are created for shading/compute purposes. This PR will try to store vertex buffers, index buffers and storage buffers on device memory to improve the performance. Uniform buffers are still located on host memory as they can be uploaded during binding process. This can (will) reset the graphics pipeline triggering draw calls using unattached resources. In future this could be optimized further as in: * using different pools for allocating specific buffers, with a fallback when buffers cannot be stored on the GPU anymore. * store uniform buffers in device memory Pull Request: https://projects.blender.org/blender/blender/pulls/115343
