Thread: pgsql: injection_points: Add routine able to drop all stats

injection_points: Add routine able to drop all stats

This serves as an example of how to use the new function introduced in
ce5c620fb625, pgstat_drop_matching_entries(), with a callback able to
filter the entries dropped.

A SQL function named injection_points_stats_drop() is added with some
tests.
