Add Prepare and Process Proposal ABCI++ methods (tendermint#631)

* abci: PrepareProposal (tendermint#6544) * regenerate mocks, proto, mod/sum, and clean up remaining preprocesstxs * fix tests and revert to old go.mod * mockery * add processproposal proto/boilerplate/logic * gofmt * fix test * move UNKNOWN response behaviour to reject * fix test and add testing util code * pass full block data when proposing or processing proposals * linter * add the process proposal method to the e2e app * add missing kvstore abci method * pass block data and results for bass app * use correct kvstore process logic for kvstore app * remove linting comment Co-authored-by: Ismail Khoffi <[email protected]> * formatting Co-authored-by: John Adler <[email protected]> * use go generate instead of make mockery * add link Co-authored-by: Marko <[email protected]> Co-authored-by: mconcat <[email protected]> Co-authored-by: Ismail Khoffi <[email protected]> Co-authored-by: John Adler <[email protected]>
