Add prog.Ref Type that serves as a proxy for real types and allows to deduplicate Types in generated descriptions. The Ref type is effectively an index in an array of types. Just before serialization pkg/compiler replaces real types with the Ref types and prepares corresponding array of real types. When a Target is registered in prog package, we do the opposite operation and replace Ref's with the corresponding real types. This brings improvements across the board: compiler memory consumption is reduced by 15%, test building time by 25%, descriptions size by 33%.
