[NONEVM-3263] Add ownable go bindings

NONEVM-3263

[Copilot]

Pull request overview

This PR refactors ownership-related bindings by extracting the Ownable2Step struct from the common package into a dedicated ownable2step package. The new package provides a more comprehensive implementation including storage types, message types, exit codes, and getter functions for ownership management in TON smart contracts.

Key Changes:

• Created a new ownable2step package with complete bindings for two-step ownership functionality
• Replaced all references from common.Ownable2Step to ownable2step.Storage across the codebase
• Added support for ownership transfer messages, error codes, and getter methods
