Fix copying of multisample images

Multisample images can be copied to other multisample images with the same number of samples, without undergoing multisample resolve. We were using the Blitter::copy() code path both for vkCmdCopyImage and attachment resolve operations at the end of subpasses, leading to resolve operations happening on copy commands. They are now detangled and copy() is able to handle multiple samples the same way as 3D slices.
