[label_matches] Add new functions label_matches(), filter_labels_include() and filter_labels_exclude()

Add a new function 'label_matches(target_label, label_patterns)' that
can be used to test if a given GN label matches any of the given label
patterns.

Add a new pair of functions:
 - 'filter_labels_include(labels, label_patterns)'
 - 'filter_labels_exclude(labels, label_patterns)'

These returns all labels in the first list that match (or don't match,
respectively) any of the patterns in the second list (much like the
'filter_include()' and 'filter_exclude()' functions do for files.
