py: Generate complete dicts in event_names.py

Before, the generated dictionaries in event_names.py just had the bits
to name mapping and a loop to add the name to bits mapping using items()
afterwards. As of Python 3 items() returns a view, not a copy, resulting
in an error as the dictionary was modified in place.

Now, generate both the bits to name and name to bits mapping when
creating event_names.py and make the loop obsolete.
