pgstat: Schedule per-backend pgstat shutdown via before_shmem_exit().

Previously on_shmem_exit() was used. The upcoming shared memory stats patchuses DSM segments to store stats, which can not be used after thedsm_backend_shutdown() call in shmem_exit().The preceding commits were required to permit this change. This commit issplit off the shared memory stats patch to make it easier to isolate problemscaused by the ordering changes rather than the much larger changes in wherestats are stored.Author: Andres Freund <andres@anarazel.de>Author: Kyotaro Horiguchi <horikyota.ntt@gmail.com>Discussion:https://postgr.es/m/20210405092914.mmxqe7j56lsjfsej@alap3.anarazel.deDiscussion:https://postgr.es/m/20210802164124.ufo5buo4apl6yuvs@alap3.anarazel.deDiscussion:https://postgr.es/m/20210803023612.iziacxk5syn2r4ut@alap3.anarazel.de
