* baseapp, client: reject gRPC connections with out-of-range/nefarious x-cosmos-block-height values
Rejects gRPC connections that send out-of-range x-cosmos-block-height
values that previously weren't checked for. We now reject any negative
values and any value greater than max(int64) aka >9223372036854775807.
Also added an enforcement for returning an error if any negative heights
are passed into (*BaseApp).createQueryContext.
Fixes#7662
