CHIA-886: Redesign ToClvm and FromClvm to be generic over Encoder and Decoder

[Rigidity]

Makes a few changes:

• ToClvm is generic over Encoder rather than Node.
• FromClvm is generic over Decoder rather than Node.
• ToNodePtr and FromNodePtr have been removed since they are no longer needed.
• Program can now implement ToClvm<Allocator> and FromClvm<Allocator> directly.
• Encoder now has a method for encode_bigint and encode_atom takes a clvmr::Atom instead of &[u8].
