Cook-off probability and cook-off tweaks (#5585)

Browse Source 
* Added cookoff probability for vehicles. Tweaks to cookoff to stop total blocking of destruction in some cases.

* Changed var name to probability. Better method for getting config value.

* Fixed naming error

* Changed setting to be a global coefficient. Added some info to cookoff doc

* Reverted hitfuel check

* Reverted damage threshold for cook-off

* Tweaked probability calculation

* Update fnc_handleDamage.sqf

```
VEHICLE setVariable ["ace_cookoff_enable", false, true];
```
## 2. Cook off probability
You can set the probability of cook off for individual vehicle types by changing the `ace_cookoff_probability` value in the vehicle's config:
```
class MyVehicle {
ace_cookoff_probability = 0.6;
};
```
Global cook off probability can also be adjusted with the `ace_cookoff_probabilityCoef` mission setting.
Higher values will make cook-off more probable, whilst lower values will make cook-off less probable.
