Implement VK_KHR_depth_stencil_resolve

This extension allows users to pass depthstencil attachments that
vkCmdResolveImage will resolve to in addition to its other resolve
operations. Only the mandatory resolve modes
"VK_RESOLVE_MODE_SAMPLE_ZERO_BIT" and "VK_RESOLVE_MODE_NONE" are
supported.

It's trivial to support both independent resolve modes since we must
resolve depth and stencil attachments separately due to how depth and
stencil attachments are stored internally.
