[kingpinXD]

The logic Unlock a ZRC20 through a precomipile is present here

https://github.com/zeta-chain/zeta-node/blob/5fd8314fa090009cc968a4227c9e79f861a102cb/precompiles/bank/method_withdraw.go#L75-L116

This can be extracted to a MsgDepositZRC20
The MsgWithdrawZRC20 can be then called from the precompile using the fungible keeper

	msgServer := fungibleKeeper.NewMsgServerImpl(&c.fungibleKeeper)
	res, err := msgServer.WithdrawZRC20(ctx, &fungibleTypes.MsgWithdrawZRC20{}

Expected Outcomes

• MsgWithdrawZRC20 is defined
• Unit Tests and Simulation tests present for MsgWithdrawZRC20
