Allow pg_read_all_stats to read pg_stat_progress_*

Hi!

One of our users asked me why they cannot read details of pg_stat_progress_vacuum while they have pg_read_all_stats role.
Maybe I'm missing something, but I think they should be able to read stats...

PFA fix.
This affects pg_stat_progress_analyze, pg_stat_progress_basebackup, pg_stat_progress_cluster, pg_stat_progress_create_index and pg_stat_progress_vacuum.

With patch
postgres=# set role pg_read_all_stats ;
postgres=> select * from pg_stat_progress_vacuum ;
pid | datid | datname | relid | phase | heap_blks_total | heap_blks_scanned | heap_blks_vacuumed | index_vacuum_count | max_dead_tuples | num_dead_tuples
-------+-------+----------+-------+---------------+-----------------+-------------------+--------------------+--------------------+-----------------+-----------------
76331 | 12923 | postgres | 1247 | scanning heap | 10 | 1 | 0 | 0 | 2910 | 0
(1 row)

Without patch
postgres=# set role pg_read_all_stats ;
SET
postgres=> select * from pg_stat_progress_vacuum ;
pid | datid | datname | relid | phase | heap_blks_total | heap_blks_scanned | heap_blks_vacuumed | index_vacuum_count | max_dead_tuples | num_dead_tuples
-------+-------+----------+-------+-------+-----------------+-------------------+--------------------+--------------------+-----------------+-----------------
76331 | 12923 | postgres | | | | | | | |
(1 row)

Thanks!
