Add new message Deposit ZRC20 in the fungible module

[kingpinXD]

The logic to Lock a ZRC20 through a precomipile is present here

https://github.com/zeta-chain/zeta-node/blob/5fd8314fa090009cc968a4227c9e79f861a102cb/precompiles/bank/method_deposit.go#L62-L110

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

	msgServer := fungibleKeeper.NewMsgServerImpl(&c.fungibleKeeper)
	res, err := msgServer.DepositZRC20(ctx, &fungibleTypes.MsgDepositZRC20{}

Expected Outcomes

• MsgDepositZRC20 is defined
• Unit Tests and Simulation tests present for MsgDepositZRC20

Can we please add a description of the problem? We should avoid adding new messages if not necessary

It would be worth spending some time investigating an alternative.

I see it as a bad idea to implement this and #3311, #3310

Messages are a lot of LoC and we shouldn't bring more in the codebase that is already complex for the sake of simulation. Same as you don't add more method in the public API of a Go package to help with tests.

We should check if there are way to extend the simulation framework to run eth txs or smth else
