Shouldn't layered drivers (as in VK_MSFT_layered_driver extension support) be reported only if VK_MSFT_layered_driver extension support is requested during vkCreateInstance?

Description

With recent loader updates and MSFT changes, we see workloads broken on repeated LUIDs, when Windows exposes layered drivers.

Old workloads does not need to be aware of the presence of layered drivers, and those should not be exposed, unless workload specifically asks for one (for example, by enabling VK_MSFT_layered_driver extension in VkInstanceCreateInfo).

Research direction

Start by reading the Vulkan specification sections for vkCreateInstance, VkInstanceCreateInfo, and VK_MSFT_layered_driver. Compare the documented extension-reporting behavior with the repeated-LUID workload problem described here. Done means the specification clearly defines whether layered drivers are reported only when the extension is requested and resolves the compatibility behavior for older workloads.
