fix(wayland): get surface extent from window instead of surface properties

On Wayland, VkSurfaceCapabilitiesKHR::currentExtent typically returns
{0xFFFFFFFF, 0xFFFFFFFF}, indicating that the application determines
the surface size rather than the compositor.
This patch fixes the issue by getting the actual surface extent from
the platform window on Wayland, ensuring the swapchain is properly
recreated with the correct dimensions.
