背景
PostgreSQL 14 preview - 活跃会话pg_stat_activity、进程进度条pg_stat_progress* 、等待事件wait_event等 信息 从 pgstat 代码 拆出
pgstat.[ch] c文件和h头文件分别拆到:
- backend_progress.[ch]
- backend_status.[ch]
- wait_event.[ch]
很赞很工整.

Split backend status and progress related functionality out of pgstat.c.
Backend status (supporting pg_stat_activity) and command
progress (supporting pg_stat_progress*) related code is largely
independent from the rest of pgstat.[ch] (supporting views like
pg_stat_all_tables that accumulate data over time). See also
a333476b925.
This commit doesn't rename the function names to make the distinction
from the rest of pgstat_ clearer - that'd be more invasive and not
clearly beneficial. If we were to decide to do such a rename at some
point, it's better done separately from moving the code as well.
Robert's review was of an earlier version.

Split wait event related code from pgstat.[ch] into wait_event.[ch].
The wait event related code is independent from the rest of the
pgstat.[ch] code, of nontrivial size and changes on a regular
basis. Put it into its own set of files.
As there doesn't seem to be a good pre-existing directory for code
like this, add src/backend/utils/activity.
