Switch PgStat_Kind from an enum to a uint32 type
A follow-up patch is planned to make cumulative statistics pluggable,
and using a type is useful in the internal routines used by pgstats as
PgStat_Kind may have a value that was not originally in the enum removed
here, once made pluggable.
While on it, this commit switches pgstat_is_kind_valid() to use
PgStat_Kind rather than an int, to be more consistent with its existing
callers. Some loops based on the stats kind IDs are switched to use
PgStat_Kind rather than int, for consistency with the new time.
