This change set implements the most recent version of `FinalizeBlock`. 

# What does this change actually contain?

* This change set is rather large but fear not! The majority of the files touched and changes are renaming `ResponseDeliverTx` to `ExecTxResult`. This should be a pretty inoffensive change since they're effectively the same type but with a different name.
* The `execBlockOnProxyApp` was totally removed since it served as just a wrapper around the logic that is now mostly encapsulated within `FinalizeBlock`
* The `updateState` helper function has been made a public method on `State`. It was being exposed as a shim through the testing infrastructure, so this seemed innocuous.
* Tests already existed to ensure that the application received the `ByzantineValidators` and the `ValidatorUpdates`, but one was fixed up to ensure that `LastCommitInfo` was being sent across.
* Tests were removed from the `psql` indexer that seemed to search for an event in the indexer that was not being created.

# Questions for reviewers
* We store this [ABCIResponses](5721a13ab1/proto/tendermint/state/types.pb.go (L37)) type in the data base as the block results. This type has changed since v0.35 to contain the `FinalizeBlock` response. I'm wondering if we need to do any shimming to keep the old data retrieveable?
* Similarly, this change is exposed via the RPC through [ResultBlockResults](5721a13ab1/rpc/coretypes/responses.go (L69)) changing. Should we somehow shim or notify for this change?
