add CCIPEncodingUtils contract and gethwrapper

RyanRHall commented 1 month ago

Motivation

I encountered a scenario w/ RMN where offchain needs to abi.encode a struct that is not included in any public contract functions (as input param or return value) and so it is not a part of the ABI or the go wrapper. Offchain is currently doing a manual encoding by re-defining the type, which I usually try to avoid at all costs. In the past, we've used a Utils contract (ex here from automation) to expose all private structs in public functions so that offchain components can use E2E type safety when encoding / decoding.

Solution

Create a CCIPEncodingUtils contract and accompanying gethwrapper
