Add a default gate set conversion transpiler for STAR architecture {H, RZ, CNOT}.
Simplify RotationSetTranspiler by using GateSetConversionTranspiler.
Slightly enhanced rotational gate optimization for GateSetConversionTranspiler (normalization of rotation angle, removal of gates with zero rotation angle).
