[Request] Implement `SecureStateDriver`

[peterkmg]

ClassicAPI already backports the frame attribute system and attribute-driven click actions. It would be useful to complete that surface with state drivers.

• Current FrameXML implementation
• Older FrameXML implementation
• SecureStateDriver overview

This can be implemented independently in Lua, but it will be beneficial to have a single shared standardized approach, and cover missing compatibility layer.
