mon, osd: add command to remove invalid pg-upmap-primary entries

The current rm-pg-upmap-primary command checks that the pgid exists
in the pgmap before continuing to remove it. Due to https://tracker.ceph.com/issues/66867,
some invalid pg-upmap-primary entires may exist for pools that have been removed.
Currently, these mappings are impossible to remove since the pgids no longer
exist in the pgmap.

This new command, rm-pg-upmap-primary-all, allows users the ability to remove
any and all pg-upmap-primary mappings in the osdmap at once, which includes
valid and invalid entries.

This command may also be helpful when upgrading from versions where users
are plagued by https://tracker.ceph.com/issues/61948. Users may use an upgraded
mon to remove all pg-upmap-primray entries (valid and invalid) so they continue
to upgrade to a safe version.
