Add new vehicleburnblowup special property

[Xenius97]

Fixes #4522

This PR fixes cars (and helis in some cases) still blowing up after burn explosions are disabled.
Now they will burn forever, and won't explode.

Hi. This isn't what "vehicleburnexplosions" property is for. This property shouldn't prevent vehicles from exploding. We have other functions for this. It disables additional explosions created for aircraft during burning (it's in the description of this property). The aircraft has to explode in the end like any other vehicle.

This fixes not existing issue.

There is a good argument about renaming this property since the name can be misleading (although "burn explosions" is quite literally about explosions during burning).
