Support Bitcoin with Protocol contract v2 architecture

[lumtis]

Describe the Issue

• Define some logic allow to set ProtocolContractVersions == 2 in the vote inbound in inbound.go
• Set the correct message: the message passed in VoteInbound is not the message itself, it doesn't contains the receiver as first few bytes anymore, this parsing should be done at the ZetaClient level
• Add E2E test to check Deposit and DepositAndCall

IMPORTANT: Bitcoin should still use the Origin field for the context for calls has the sender field (ethaddress) can't contains the address : #3018 (comment)

Will wait on #3358 before starting it. Basically if the receiver address is not correctly formatted in the Bitcoin observation, this would results in an "invalid observation" that would reverts the funds to the user
