GrpcOrGrpcWebClientChannel class
A client channel that underneath uses gRPC ClientChannel on all platforms except web, on which it uses GrpcWebClientChannel.
Note that gRPC and gRPC-web are 2 different protocols and server must be able to speak both of them for this to work. Depending on its exact setup, the server may expose gRPC and gRPC-web on the same port (this is the standard setup of AspNetCore implementation for example), on separate ports of the same host (common setup of in-process gRPC-web to gRPC proxies or colocated Envoy gRPC-web to gRPC proxy), or as a completely separate endpoints (for example if Envoy and gRPC server are exposed as different kubernetes services). A corresponding constructor is provided for each case.
