Lower vkAcquireNextImageKHR() timeout to 500 milliseconds.

The timeout specifies how long Vulkan waits for the next frame becoming
available. On the one hand we need to take the vsync or the possibility
that we get scheduled away for longer times into account. On the other
hand we don't want to wait for too long, the game may run into the
timeout after its windows was minimized, etc. 500 milliseconds sounds
like a good compromise.

// for VK_OUT_OF_DATE_KHR and VK_SUBOPTIMAL_KHR it'd be fine to just rebuild the swapchain but let's take the easy way out and restart Vulkan.
