CustomEntitlement -> CrossChainEntitlement implementation in go (#1083)

The `ICrossChainEntitlement` type replaces `ICustomEntitlement` and
takes an abi-encoded byte array of parameters that is decoded by the
contract according to it's own application-specific logic.

This PR migrates the ISENTITLED check type to expect
ICrossChainEntitlement interfaces for ISENTITLED contracts and uses the
v2 check type to encode the parameter byte array for passing directly to
the contract.

A follow-up PR will be released that implements the typescript change
and re-enables e2e tests to complete #1046.
