Context

Following discussion on slack (https://tezos-dev.slack.com/archives/GB0UR34N8/p1610964757049700), this MR updates the usages of protocol types outside of the protocol to abstract (Alpha_context) types, rather than concrete (*_repr) types.

This avoid difficulties with conversions between abstract and concrete types.
