Add PgStat_KindInfo.init_shmem_cb This new callback gives fixed-numbered stats the possibility to take actions based on the area of shared memory allocated for them.
This removes from pgstat_shmem.c any knowledge specific to the types of fixed-numbered stats, and the initializations happen in their own files. Like b68b29bc8fec, this change is useful to make this area of the code more pluggable, so as custom fixed-numbered stats can take actions after their shared memory area is initialized.
