Add padding between slices

When doing multisample rendering, we need to avoid conflicts between
render target writes to adjacent slices.

- Worst case is an unaligned 16-byte write hitting the last byte of the image, + 15 bytes beyond
- Ensure that slices are always 16-byte aligned

Test: dEQP-VK.renderpass.*
