Improve the description of XLOG_RUNNING_XACTS.

Previously, the description of XLOG_RUNNING_XACTS showed onlytop-transaction XIDs and whether subtransactions overflowed. This commitimproves it to show individual subtransaction XIDs. This also improves thedescription of overflowed subtransactions.This additional information can be helpful for testing and debuggingpurposes.Author: Masahiko SawadaReviewd by: Fujii Masao, Kyotaro Horiguchi, Ashutosh Bapat, Bharath RupireddyDiscussion:https://postgr.es/m/CAD21AoAqvaE+XEeXHHPdAGQPcCoGXxuoeutq_nWhUSQvTt5+tA@mail.gmail.com
