Vulkan: Reduce Framebuffer dirtyBits for swapchain only changes For window system framebuffer, the change to it is very limited. Most time it is only swapchain image changes. Right now we are also setting depth/stencil buffer dirty and processing layer count update and color mask and blending update when only color image changed. This CL avoids setting depth/stencil dirty bit for swap chain image changes. It also avoids color mask and blending update (they still gets updated for draw buffer change or draw franmebuffer binding changes).
