Move Inside/outside and daytime/nighttime to a property of a sound instead of a dedicated sound

[Fris0uman]

Is your feature request related to a problem? Please describe.

Currently there is only one sound for being inside and one inside_rain to play if it rains outside but nothing for the other weather pattern.
Same thing for daytime/nightime those don't interact with weather or being inside or out.

And weather that you should mainly here when you're outside keeps playing when you're inside

Solution you would like.

Similar to #52295 and it's solution #52308

Add a is_night bool that default to false to sounds so that they can differ at night
Add a similar is_inside to replace Inside/outside entries

Obsolete the hardcoded sound for inside,outside night and day because they should be covered by the various weather effect instead now.

Describe alternatives you have considered.

Use flags instead of bool

"flags": [ "NIGHT", "INSIDE" ]
