Vulkan: Request at least 3 images for MAILBOX. The glmark2 benchmark score went down (on Android with Pixel devices) when ANGLE changed VkSwapchainCreateInfoKHR::minImageCount from 3 down to 2, when using VK_PRESENT_MODE_MAILBOX_KHR. In experimenting, this was confirmed. This CL changes minImageCount back to 3. Vulkan spec issue #1671 was filed in order to understand whether this is a good/bad approach for other drivers/platforms. Test: glmark2 on Pixel2.
