Mop-up for wait event naming issues.
Synchronize the event names for parallel hash join waits with other event names, by getting rid of the slashes and dropping "-ing" suffixes. Rename ClogGroupUpdate to XactGroupUpdate, to match the new SLRU name. Move the ProcSignalBarrier event to the IPC category; it doesn't belong under IO. Also a bit more wordsmithing in the wait event documentation tables. Discussion: https://postgr.es/m/4505.1589640417@sss.pgh.pa.us
