gitk: Add user preference to hide custom references

External tools such as Jujutsu may add many references that are of no
interest to the user. This preference hides them.

The non-custom refs are those that pass git's default decoration filter
(see set_default_decoration_filter), bisect/*, and rewritten/*.

The preference is off by default, maintaining current behavior.
