Fix BAG2 slow views by using common objectid sequence

[matthijsln]

BRMO-192

• objectid sequence for all objectid columns so rows from tables can be combined in view but row number does not need to be used, speeding up non-materialized views
• reverse geometrie_centroid and geometrie columns, so on-the-fly calculated column is not used for TailorMap geometry queries

Update instructions should include that the BAG2 views should be recreated using the scripts (208_bag2_views.sql and 209_bag2_rsgb_views.sql) that get included in the installation scripts.
