This commit makes the following changes: - Introduces a new `load_instrumentor(EntryPoint) -> None:` with a default implementation method to the `BaseDistro` class. - The default implementation loads the insrumentor from the provided entry point and calls applies it without any arguments. (same as before) - sitecustomize now calls Distro's `load_instrumentor` method to load and activate an instrumentor instead of doing it directly. - Added a new `DefaultDistro` implementation which is used if not distro is found by entry points.
