This pull request includes significant changes to the TEN Framework to simplify the addon and protocol management by removing asynchronous instance creation and destruction functions and adding new protocol-related structures and functions.

Simplification of Addon Management:

• Removed asynchronous instance creation and destruction functions and replaced them with synchronous versions in core/include/ten_runtime/addon/addon.h.
• Removed related asynchronous functions and structures from core/include_internal/ten_runtime/addon/addon.h. [1] [2] [3]
• Updated the addon initialization and creation functions to use the new synchronous instance functions in core/src/ten_runtime/addon/addon.c. [1] [2] [3]

Protocol Management Enhancements:

• Added new structures and functions for protocol creation and management in core/include_internal/ten_runtime/addon/protocol/protocol.h. [1] [2]
• Introduced new protocol-related callback and info structures in core/include_internal/ten_runtime/engine/internal/remote_interface.h. [1] [2]
• Added protocol-related functions and structures to handle protocol creation completion in core/include_internal/ten_runtime/app/on_xxx.h and core/include_internal/ten_runtime/engine/on_xxx.h. [1] [2] [3]

Miscellaneous Changes:

• Removed deprecated functions related to extension creation and destruction in core/include/ten_runtime/addon/extension/extension.h. [1] [2]
• Updated the ten_engine_t structure to include a reference to ten_env_t in core/include_internal/ten_runtime/engine/engine.h. [1] [2]
• Removed deprecated protocol creation function in core/include/ten_runtime/protocol/protocol.h.
• Simplified endpoint functions in core/include_internal/ten_runtime/app/endpoint.h.
