feat(goctl): add rpc_name flag for generating rpc service code

[gszw90]

Add the --rpc_name flag to the goctl rpc protoc command to set the RPC service name instead of using the proto file name.
It also allows to generate rpc service code from multiple proto files within the same service.
run:

goctl rpc protoc app/pb/user.proto --go_out=./app/pb --go-grpc_out=./app/pb --zrpc_out=./app --style=go_zero -m --rpc_name app
goctl rpc protoc app/pb/role.proto --go_out=./app/pb --go-grpc_out=./app/pb --zrpc_out=./app --style=go_zero -m --rpc_name app

generate files:

Pull Request Overview

This PR adds a new --rpc_name flag to the goctl rpc protoc command, allowing users to specify a custom RPC service name instead of defaulting to the proto file name. This enables generating RPC service code from multiple proto files within the same service by providing a unified service name.

• Adds --rpc_name flag to override default service naming behavior
• Modifies generators to use the custom RPC name when provided
• Updates documentation and help text for the new flag

The comment has a grammatical error. It should be "VarStringRpcName describes the rpc name" (missing 's' in 'describe').

Suggested change

	// VarStringRpcName describe the rpc name
	// VarStringRpcName describes the rpc name

Use name instead of rpc_name?
