Mock ICD should either report 1.1 support, or fix UpdateAfterBind limits

Context: https://gitlab.khronos.org/vulkan/vulkan/-/issues/3324

The Vulkan spec has this regarding UpdateAfterBind limits:

The UpdateAfterBind descriptor limits must each be greater than or equal to the corresponding non-UpdateAfterBind limit.

However, the Mock ICD doesn't fill these values and returns 0. This results in validation layers when using the Mock ICD and asking for Vulkan version > 1.1, even though Mock ICD advertises support for the latest version:

    pProperties->apiVersion = VK_HEADER_VERSION_COMPLETE;

Either the Mock ICD should advertise only Version 1.1 or (better yet) fix these limits.

@ShabbyX we have had issue in the Validation Layers where MockICD doesn't return non-zero values, but then the question became

What should it return instead?

There is no "default" value in the XML to know what maxPerStageDescriptorUpdateAfterBindUniformBuffers needs to be minimum (I am currently tasked with help getting this generated https://gitlab.khronos.org/vulkan/vulkan/-/issues/3211)

but until then, the Validation Layers testing decided to use the new Profile Layer to have it return these limit values and just use MockICD to consume the Vulkan calls

Was that informational, or is there a question I should be answering? FYI, this is in the bottom of priority list for us

informational, this is higher on my priority to fix for us and taking notes for myself later 😄
