vulkan/wsi/wayland: use roundtrip instead of flush on swapchain free

Browse source 
Use wl_display_roundtrip() instead of wl_display_flush() when freeing
a swapchain to ensure the compositor has processed buffer release
events before continuing.

wl_display_flush() only sends pending requests without waiting for
the compositor to process them. When rapidly creating and destroying
large swapchain buffers, buffer references may not be released quickly
enough (e.g., during CTS testing), causing memory to accumulate.

Using wl_display_roundtrip() ensures synchronization with the
compositor, allowing buffers to be released promptly.
