Manos Koukoutos 8bb8bfdefc [wasm-gc] Remove rtts with depth 
Since inheritance depth of every type is known in the isorecursive
hybrid type system, rtts with depth are removed. This enables
simplification of type checks in Liftoff and Turbofan, as well as
decoding of object allocation instructions.
