doc: Add better description for rewrite functions in event triggers
There are two functions that can be used in event triggers to get more details about a rewrite happening on a relation. Both had a limited documentation: - pg_event_trigger_table_rewrite_reason() and pg_event_trigger_table_rewrite_oid() were not mentioned in the main event trigger section in the paragraph dedicated to the event table_rewrite. - pg_event_trigger_table_rewrite_reason() returns an integer which is a bitmap of the reasons why a rewrite happens. There was no explanation about the meaning of these values, forcing the reader to look at the code to find out that these are defined in event_trigger.h. While on it, let's add a comment in event_trigger.h where the AT_REWRITE_* are defined, telling to update the documentation when these values are changed. Backpatch down to 13 as a consequence of 1ad23335f36b, where this area of the documentation has been heavily reworked.
