Implement gRPC Simulate endpoint (cosmos#7035)

* Implement simulate endpoint

* Add GetProtoTx()

* Add signing in test

* Add txBuilderFromProto

* Remove stray println

* Update to master

* Merge master

* Fix tests

* Make tests pass

* Integrate in router

* Make proto-gen

* Fix lint

* Really fix lint

* Refactor to fix import cycles

* Rename builder -> wrapper

* Update proto/cosmos/base/reflection/v1beta1/reflection.proto

* Fix after merge

* t->w
