Enable instance extensions
requested to merge angeliki.tsintzira/vulkan-wsi-layer:vulkan_wsi_enable_instance_extensions into main
Modify the layer so that instance extensions needed for Wayland are only enabled when Wayland is selected.
In the past, the layer was changed to explicitly enable the instance extensions it needs in the intercepted calls to vkCreateInstance. Therefore, the layers always enabled the extension VK_KHR_external_memory_capabilities, despite this is only required by Wayland.
In this patch, this extension is only enabled when Wayland is enabled, i.e. when VK_KHR_wayland_surface is part of the extensions passed to vkCreateInstance.
