Advertise VK_KHR_depth_stencil_resolve extension on all devices.

Advertise VK_KHR_depth_stencil_resolve extension on early iOS devices,
since VK_RESOLVE_MODE_SAMPLE_ZERO_BIT is supported on all devices,
even if other resolve modes are not, and makes it consistent with
Vulkan 1.2 mandatory support for VK_RESOLVE_MODE_SAMPLE_ZERO_BIT.
