This patch adds two new counters to pg_stat_statements:
- generic_plan_calls
- custom_plan_calls
These counters track how many times a prepared statement was executed
using a generic or custom plan, respectively, providing a global
equivalent at query level, for top and non-top levels, of
pg_prepared_statements whose data is restricted to a single session.
This commit builds upon 92b273de39. The module is bumped to version
1.13. PGSS_FILE_HEADER is bumped as well, something that the latest
patches touching the on-disk format of the PGSS file did not actually
bother with since 2022..
