Vulkan/Android: Workaround weird WSI return codes in landscape mode.

Browse Source 
Android WSI wants you to use preTransform, and if it is not used
correctly, Android 10 will return VK_SUBOPTIMAL_KHR, and we would create
a new swapchain every frame.

This workaround just ignores this error, since it's not really an error.
A more "proper" fix is to use prerotate and modify the MVP matrices,
which might help certain devices with crummy display processors.
