Add write_to_file to PgStat_KindInfo for pgstats kinds
This new field controls if entries of a stats kind should be written or
not to the on-disk pgstats file when shutting down an instance. This
affects both fixed and variable-numbered kinds.
This is useful for custom statistics by itself, and a patch is under
discussion to add a new builtin stats kind where the write of the stats
is not necessary. All the built-in stats kinds, as well as the two
custom stats kinds in the test module injection_points, set this flag to
"true" for now, so as stats entries are written to the on-disk pgstats
file.
