PG-435: Adding new counters that are available in PG15 (#329) 

In line with pg_stat_statments for PG15, This commit adds eight new cumulative
counters for jit operations, making it easier to diagnose how JIT is used in an
installation. And two new columns, temp_blk_read_time, and temp_blk_write_time,
respectively, show the time spent reading and writing temporary file blocks
on disk.
Moreover, The commit also contains a few indentations and API adjustments.
