As with vkCmdCopyImageToBuffer, this implements a fast path using the TLB for the case where we are copying images from offset (0, 0). We don't have the fallback path for other cases yet. For this we need to rethink a bit our loads and stores so we can handle depth/stencil copies correctly. Specifically, we are expected to do different things depending on whether we are copying to a linear buffer or to an image. When copying depth/stencil to a buffer, we can only copy one aspect at a time and the result should be tightly packed in the destination buffer. When copying depth/stencil to an image, we can copy one or both aspects, and we need to write them in the corresponding aspect of the destination image. Because we can't do stores from the Z/S tile buffers in raster format, we need to do image to buffer copies of these aspects using the a color tile buffer and a compatible color format. However, when we are copying to another image, since we need to write the channels in the corresponding aspect of the destination image, we need to do this using by loading and storing from an appropriate Z/S tile buffer.
