NativeSwapChainImplVk: Remove unnecessary transition on Configure

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.
