Vulkan: Fix mid-RP draw clear w.r.t growing scissor UtilsVk::clearFramebuffer didn't grow the render area if scissor had grown. FramebufferVk::clearWithCommand does that and is unaffected by the bug. Normally, ContextVk::updateScissor grows the render area automatically, but clear is special in that it's not affected by the viewport while ContextVk::updateScissor is.
