Introduced ALPN (Application-Layer Protocol Negotiation) support in t…

…he SSL/TLS context and connection handling.

Added new constants, types, and functions to manage ALPN protocols.
Implemented ALPN callback functions and integrated them into the server and client examples.
Updated the Ctx struct to include an ALPN callback and provided methods to set ALPN protocols.
Enhanced the client to specify and negotiate ALPN protocols.
Added a method to retrieve the negotiated ALPN protocol from a connection.
Fixed minor typos in existing constants.
