Document XLOG_INCLUDE_XID a little better
I noticed that commit 0bead9af484c left this flag undocumented in XLogSetRecordFlags, which led me to discover that the flag doesn't actually do what the one comment on it said it does. Improve the situation by adding some more comments. Backpatch to 14, where the aforementioned commit appears.
