[repository] Drop type_and_source_from_eid and rename related cache We don't want to handle anymore the entities.asource column so we shouldn't use those anymore. Also rename repository's _type_source_cache into _type_extid_cache as this is what it's containing now. Do similar renaming to the system source API. Related to #15538288

for table, column in [
        ('transactions', 'tx_time'),
        ('tx_entity_actions', 'tx_uuid'),
        ('tx_relation_actions', 'tx_uuid')]:
    repo.system_source.create_index(session, table, column)
