Under XWayland, the first present after a window resize is sometimes
completed with COPY (seems to happen when the previous present with the
old size is pending; not really sure). The following presents are
completed with FLIP.
When a swapchain is created with an old swapchain, and
old_chain->last_present_mode is FLIP, chain->last_present_mode is set to
FLIP as well. This causes the new swapchain to be marked
VK_SUBOPTIMAL_KHR, which is sticky, if the first present is completed
with COPY.
Instead of inheriting, treat each swapchain as independent. We will
miss the case where an old swapchain is flipping but a new swapchain is
copying. But swapchain reallocation normally happens in response to
present engine state change. If the newly allocated swapchain is
copying, another reallocation is unlikely to fix that.
