Describe the Issue

When going through the code recently, I noticed that the NoAssetCall had never been enabled for Bitcoin chain. We can see below checking in here

// NoAssetCall will be disabled for Bitcoin until full V2 support
// https://github.com/zeta-chain/node/issues/2711
if memoStd.OpCode == memo.OpCodeCall {
	return errors.New("NoAssetCall is disabled for Bitcoin")
}

Now that the V2 architecture was fully released, we should be able to enable OpCodeCall operation code and create e2e tests.
