chore: bump grpc limits to 50MB

[mudler]

Description

This pull request introduces changes to ensure consistent gRPC message size limits across various backends and client implementations. The updates set maximum message sizes to 50MB for sending, receiving, and overall message length. These changes improve the handling of large payloads and prevent errors caused by exceeding default gRPC limits.

Backend Updates

• C++ Backend (grpc-server.cpp): Added SetMaxMessageSize, SetMaxSendMessageSize, and SetMaxReceiveMessageSize to set the maximum gRPC message size to 50MB.
• Python Backends:
  • Updated serve functions in multiple files (e.g., autogptq, bark, coqui, diffusers, exllama2, faster-whisper, kokoro, rerankers, transformers, vllm) to include gRPC options for max_message_length, max_send_message_length, and max_receive_message_length, all set to 50MB.

Client Updates

• Go Client (client.go):
  • Updated multiple methods (e.g., HealthCheck, Embeddings, Predict, LoadModel, GenerateImage, TTS, AudioTranscription, etc.) to include grpc.WithDefaultCallOptions for setting MaxCallRecvMsgSize and MaxCallSendMsgSize to 50MB.
