Document XLOG_INCLUDE_XID a little better

Browse Source 
I noticed that commit 0bead9af48 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.
