[Bitcoin] Atomic state binding

[jolestar]

Provide functions for binding L2 state to L1(UTXO, Inscription)

module bitcoin_move::utxo{
  #[private_generics(S)]
  public fun add_temp_state<S: store+drop>(utxo: &mut Object<UTXO>, state: S);

  #[private_generics(S)]
  public fun remove_temp_state<S: store+drop>(utxo: &mut Object<UTXO>): S;
}

When the UTXO is spent, the Temporary Area states will be cleared.

module bitcoin_move::ord{
   #[private_generics(S)]
   public fun add_temp_state<S: drop>(inscription: &mut Object<Inscription>, state: S);

   #[private_generics(S)]
   public fun remove_temp_state<S: drop>(inscription: &mut Object<Inscription>): S;

   #[private_generics(S)]
   public fun add_permanent_state<S: store>(inscription: &mut Object<Inscription>, state: S);

   #[private_generics(S)]
   public fun remove_permanent_state<S: store>(inscription: &mut Object<Inscription>): S;
}

When the Inscription transfers, the Temporary Area states will be cleared, and the Permanent Area state will be kept.
