Vulkan: Support MSRTT depth/stencil resolve VK_KHR_depth_stencil_resolve is used by this change to resolve depth/stencil multisampled-render-to-texture renderbuffers. This extension is not widely supported yet. If it's not present, the depth/stencil resolve operation is silently ignored and the renderbuffer acts as a normal multisampled one. This is not correct, but our primary user (Chrome), and most applications don't care for the resolved depth/stencil data. In fact, it's recommended for the depth/stencil attachment to be invalidated after rendering. Exposing EXT_multisampled_render_to_texture even in the absence of depth/stencil resolve allows the majority of the applications to still take advantage of MSRTT color attachments.
