anv: Remove default scissor and viewport concepts
Users should never provide a scissor or viewport count of 0 because they are required to set such state in a graphics pipeline. This behavior was previously only used in Meta, which actually just disables those hardware operations at pipeline creation time. Kristian noticed that the current assignment of viewport count reduces the number of viewport uploads, so it is not removed.
