This adds a new virtual method `GetScriptedModulePath()` to
`ScriptedInterface` that allows retrieving the file path of the Python
module containing the scripted object implementation.
The Python implementation acquires the GIL and walks through the
object's `__class__.__module__` to find the module's `__file__`
attribute. This will be used by ScriptedFrame to populate the module and
compile unit for frames pointing to Python source files.
