Rework A Gudiña stations

[ConscritNeuneu]

The historic train station is being demolished. The new station of A Gudiña is A Gudiña – Porta de Galicia.

• Mark 23639 as is_city (even if it's slightly contentious)
• Remove renfe code and renfe_is_enabled for 23639
• Add is_main_station hint on 74642 A Gudiña – Porta de Galicia
• Mark 23639 as parent of 74642

This should prompt the renfe code to use this station when searching.
