Clarify wraparound warning percentage messages Commit e646450e609 added DETAIL messages for XID and MultiXactId wraparound warnings that described the reported percentage as the percentage of IDs available for use. However, the percentage is actually calculated from the remaining distance to the wraparound limit, not the stop limit where new IDs are refused. As a result, the wording could be misinterpreted as meaning that the reported percentage of IDs can still be allocated.
Update the wording to clarify that the reported percentage represents the remaining transaction ID space or MultiXactId space before wraparound. Also update the related XID warning hints to use "transaction ID" terminology consistently. Backpatch to v19, where the DETAIL messages were added.
