swr: [rasterizer] attribute swizzling and linkage
Add support for enhanced attribute swizzling. Currently supports constant source overrides to handle PrimitiveID support. No support yet for input select swizzling or wrap shortest. Removes obsoleted linkageMask and associated code. Signed-off-by: Tim Rowley <[email protected]>
