This adds a new permission endowment:rpc, which Snaps need in order to use the onRpcRequest handler. It takes an object in order to specify if the Snap can receive JSON-RPC requests from other Snaps, Dapps, or both.

{
  initialPermissions: {
    'endowment:rpc': {
      snaps: true,
      dapps: false, // Default value
    }
  }
}

Closes #855.
