[feat] CCIP capability config contract (#858)

## Motivation

The CCIP capability needs to fetch its configuration from somewhere -
that somewhere is the CCIP capability configuration contract.

## Solution

Implement the CCIP capability configuration contract in solidity. The
solidity implementation almost matches the design doc exactly.
