This pull request aims to make it possible to generate, format, and lint the protos within this repo.
To accomplish that end, the Dockerfile containing common tools for building the tendermint protos has been moved into this repository and several accompanying changes were made to streamline the proto generation process.

This PR implements the proto changes made in https://github.com/tendermint/spec/pull/352, removing the legacy messages that were used in the pex reactor.

## Description

- bump gogoproto (1.3.2)
- regenerate proto files

Closes: #XXX

Reorganizes the Protobuf schemas. It is mostly bikeshedding, so if something is contentious or causes a lot of extra work then I'm fine with reverting. Some Protobuf and Go import paths will change.

* Move `abci/types/types.proto` to `abci/types.proto`.

* Move `crypto/keys/types.proto` and `crypto/merkle/types.proto` to `crypto/keys.proto` and `crypto/proof.proto`.

* Drop the use of `msgs` in filenames, as "message" is a very overloaded term (all Protobuf types are messages, and we also have `message Message`). Use `types.proto` as a catch-all, and otherwise name files by conceptual grouping instead of message kind.
