Vulkan: Use correct actual FormatID for MSAA swapchain image Implementation of "overrideSurfaceFormatRGB8ToRGBA8" feature missed updating actual FormatID for the MSAA swapchain image. This bug makes possible to initialize RGBA8 swapchain image and RGB8 MSAA image. However, on practice MSAA is still RGBA8 because RGB8 renderable is generally emulated on Android. VUID-vkCmdResolveImage-srcImage-01386: srcImage and dstImage must have been created with the same image format. This fix is cosmetic and is not expected to fix any real bugs (because RGB8 is generally emulated with RGBA8).
