Overheating - Fix issues from release (#8617)

* move overheating cookoff into separate function

* move heatCoef and require mission restart for setting change

- move heatCoef to a more sensible place
- require mission restart for heatCoef setting change (it gets cached per ammo type)

* add exit to ammo temp loop if cookoffCoef is changed to 0 mid-mission

- add exit to ammo temp loop if cookoffCoef is changed to 0 mid-mission, this prevents an issue where all weapon cookoff regardless of temp, because required temp gets multiplied by cookoffCoef which has been set to 0.

* file end new line

* update header for ace_overheating_fnc_cookoffWeapon

* use ambientTemperature as floor for weapon and ammo temp

* add coolingCoef setting

* improve feature documentation

* add fnc_cookoffWeapon to XEH_PREP

* add type of jam to ace_weaponJammed local event

- add type of jam to ace_weaponJammed local event
- fix #8637

* fix misspelling

Co-authored-by: TyroneMF <TyroneMF@hotmail.com>

* clear all weapon heat on death

* Update addons/overheating/functions/fnc_updateTemperature.sqf

Co-authored-by: GhostIsSpooky <69561145+Salluci@users.noreply.github.com>

* deprecate ace_overheating_fnc_getBarrelMass, cache weapon bolt and barrel mass values

- cache closed bolt value by moving config look up to ace_overheating_fnc_getWeaponData
- cache barrel mass value by moving calculation from ace_overheating_fnc_getBarrelMass to ace_overheating_fnc_getWeaponData
- deprecate ace_overheating_fnc_getBarrelMass to be a wrapper for ace_overheating_fnc_getWeaponData that only returns barrel mass

* add public functions to get and set weapon and ammo temperature

* add `canCoolWeaponWithItem` function, workaround for #8657

* Apply suggestions from code review

Co-authored-by: PabstMirror <pabstmirror@gmail.com>

* add coef setting for addition heat from suppressor

* Update fnc_overheat.sqf

* improve fnc_canCoolWeaponWithItem

* remove extra (

* Move canCoolWeaponWithItem action code to function

* Use hashmaps and reset on settings change

* Apply suggestions from code review

 ### 2.4 Cooling your weapon
 
-- Weapons and spare barrels will cool off over time.
+- Weapons and spare barrels will cool off over time, down to the ambient temperature in the mission.
 - Cooling speed of weapons in increased in windy or rainy weather, and when swimming.
 - If ACE Field Rations is loaded then weapons can be cooled with canteens, water bottles, or other beverage items. This does not require the Field Rations system to be enabled.
 - If ACE Field Rations is enabled then weapons can also be cooled with the same water sources used to refill canteens and water bottles.
