[uss_qualifier/scenarios/netrid] Move recent positions checks to display_data_evaluator from common_data_dictionary

[mickmis]

This PR moves the 'recent positions' checks from common_data_dictionary to display_data_evaluator. This is to align check documentation with implementation, as those recent positions checks are not part of the common data dictionary.

Those checks are implemented into evaluate_sp_flight_recent_positions_times and evaluate_sp_flight_recent_positions_crossing_area_boundary.
In addition some necessary refactorings are included:

• Rename evaluate_sp_flights to evaluate_sp_flight and simplify its arguments
• Inline _evaluate_recent_position_time into evaluate_sp_flight_recent_positions_times
• Set functions _chronological_positions and _sliding_triples as static
• In _evaluate_normal_sp_observation take flight from mapping instead of from sp_observation: this avoids redoing the work of mapping a flight to a participant ID and query
