view platform: cleanup view service

[adecaro]

The goal of this Issue is to:

• Bring context.Context as first parameter of the functions getting it in input
• Introduce a way to set a timeout when running a view via RunView
• Remove the finality handler cause it is not needed anymore
• Streamline the use of local interfaces
• Remove unnecessary functions from view.Manager
• Introduce LocalFactory to create an instance of a view directly from a struct so to avoid any unnecessary struct marshaling.
