Update proto files & definitions in accordance with ADR023 (#6413)

* consolidate proto files into single directory, turn on PACKAGE_DIRECTORY_MATCH linting

* add third_party root for third party proto files

* move ibc proto files to top level folder, rename .proto files to types.proto as before

* update protocgen script, and run code generation

* move vesting proto definition to cosmos namespace, rename from types.proto in alignment with buf.build naming conventions

* update Makefile so proto dependencies are set with new structure when updated

* add comment for sed usage in makefile

* remove unused aliases of proto generated types

* add settings.json instructions to contributing.md for including protobuf paths
