Add announcement ranges to the neutral section model

[Castavo]

closes #4661

This PR:

• Adds a new list of track ranges to NeutralSections
• Uses it in order to be able to coast on some ranges but still display them in GEV as normaly electrified, as it was requested by PM team. (The electrification in GEV should be refactored some day and some of this would disappear)
• Fixes some tiny misc stuff in front linked to electrification in GEV

This PR may seem a bit large, but most lines of changes comes from the update of editoast/test/small_infra/small_infra.json

Please especially test that STDCM works fine, I'm not an expert on this part of the app, and I have some trouble diagnosing if my changes impacted it

Code looks good to me, but I can't test as the backend is broken (500 when I want to create a train, see #4871)

LGTM.
