About: feat: Add auto_encoding and improve send_compressed behavior

[m62624]

Reminder for PR #2058

When using send_compressed, the server sends compressed data even if the compression format isn't supported by both the client and the server. The server should only use supported formats or send uncompressed data.

Changes
Refactored logic to ensure the server only uses compatible compression formats.
Added auto_encoding to automatically select the correct format.

This aligns with expected gRPC behavior.
