Support gRPC reflection on the client side.

Is your feature request related to a problem? Please describe.

gRPC servers might provide this standard reflection endpoint for getting data about the service and messages provided.

This feature request is for a KMP gRPC reflection client

Describe the solution you'd like

I would like KMP client library that can be used to talk to a gRPC reflection server

This library could be used as a building block to build something similar

Use cases:

• a wasm Compose Multiplatform demo to introspect any gRPC server
• a plugin for Chucker to decode protobuf
