doc: Update track_io_timing documentation to mention pg_stat_io.
The I/O timing information collected when track_io_timing isenabled is now documented to appear in the pg_stat_io view,which was previously not mentioned.This commit also enhances the description of track_io_timingto clarify that it monitors not only block read and writebut also block extend and fsync operations. Additionally,the description of track_wal_io_timing has been improvedto mention both WAL write and WAL fsync monitoring.Backpatch to v16 where pg_stat_io was added.Author: Hajime MatsunagaReviewed-by: Melanie Plageman, Nazir Bilal Yavuz, Fujii MasaoDiscussion:https://postgr.es/m/TYWPR01MB10742EE4A6F34C33061429D38A4D52@TYWPR01MB10742.jpnprd01.prod.outlook.com
