Vulkan: Check format compatibility to enable mip levels If redefining the texture level is needed while respecifying the image storage, the base level could be incompatible with the max level count. Enabling the whole level count can cause a null pointer dereference when copying an image that does not support `pixelReadFunction`. To handle the problem, this CL checks the format compatibility and enables only the effective base level.
