feat: Add withdrawal message verification

[lukema95]

The original code did not check whether the poolId and denom of msg matched in the Withdraw function, leading to a vulnerability. Assuming Alice has two shares, ShareA and ShareB, when calling Withdraw, Alice sets the poolId in msg to the liquidity pool corresponding to ShareA but sets the denom to the denom of ShareB. In this case, the following code will not throw an error.
https://github.com/sideprotocol/side/blob/47fc3fe9642c316865b5d3f8e07a1c1389a24029/x/gmm/keeper/msg_server_withdraw.go#L28-L30
In the end, Alice will successfully obtain tokens from the liquidity pool of PoolA by decreasing the shares of PoolB.
