feat(client): add dynamic prompt (partial cherry-pick #22775)

CHANGELOG.md

@@ -75,6 +75,7 @@ Ref: https://keepachangelog.com/en/1.0.0/
 * (server) [#24072](https://github.com/cosmos/cosmos-sdk/pull/24072) Return BlockHeader by shallow copy in server Context.
 * (x/bank) [#24053](https://github.com/cosmos/cosmos-sdk/pull/24053) Resolve a foot-gun by swapping send restrictions check in `InputOutputCoins` before coin deduction.
 * (codec/types) [#24336](https://github.com/cosmos/cosmos-sdk/pull/24336) Most types definitions were moved to `github.com/cosmos/gogoproto/types/any` with aliases to these left in `codec/types` so that there should be no breakage to existing code. This allows protobuf generated code to optionally reference the SDK's custom `Any` type without a direct dependency on the SDK. This can be done by changing the `protoc` `M` parameter for `any.proto` to `Mgoogle/protobuf/any.proto=github.com/cosmos/gogoproto/types/any`.
+* [#24378](https://github.com/cosmos/cosmos-sdk/pull/24378) Added interactive autocli prompt functionality, including message field prompting, validation helpers, and default value support.
