Configure was transitioning the swapchain images from undefined to present layout but this was already happening because TextureVk starts with a mLastUsage of None that will force a transition from undefined when used. Also introduce an internal texture usage bit kPresentTextureUsage to prepare for the eventual remove of wgpu::TextureUsage::Present when old swapchains are removed.
