Adding VK_KHR_shared_presentable_image basic support
To comply with ICDs that expose the
VK_KHR_shared_presentable_image extension, the Layer needs to
handle VkSharedPresentSurfaceCapabilitiesKHR struct (holds
sType=VK_STRUCTURE_TYPE_SHARED_PRESENT_SURFACE_CAPABILITIES_KHR)
for queries on the VkSurfaces managed by the Layer.
A simple implementation that sets the minimum required flags is
provided in this commit.
Since no WSI layer swapchain will support the shared presentable modes,
no other functionality is required. VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT
must be included in the sharedPresentSupportedUsageFlags field but
implementations may support additional usages.
