  grass.temporal: Add registered_maps_grouped() and honor dbif mapsets in tlist() (#7714)

Add a gui_support helper that returns the maps registered in all space
time datasets of the mapsets covered by the given database connection,
grouped by dataset type and dataset id, ordered by start time. This
gives the Data Catalog a cheap way to show dataset contents and to
identify maps registered in any dataset without calling t.rast.list
per dataset.

Fix tlist() to iterate the mapsets of the passed connection instead of
re-deriving the search path, so tlist_grouped() works with a
connection created with mapsets=*. Default behavior is unchanged.

The tests also cover mapsets without a temporal database, a project
without any temporal database, and verify that listing with
tgis.init(skip_db_init=True) does not create a temporal database.
