Core/Misc: dropped obsolete GameObject::GetGameObject method
Removed redundant cast to c_str() in ConfigMgr::Reload function.

cppcheck performance warning:
[src/server/shared/Configuration/Config.cpp:62]: (performance) Passing the
result of c_str() to a function that takes std::string as argument no. 1 is
slow and redundant.

Scripts/Commands: Allow to set a custom duration to the Freeze command applied Aura

- Allow to set a default duration for the Freeze Aura in worldserver.conf
- Handle the .freeze and .unfreeze command custom effects through the Freeze AuraScript
- Make players able to eventually unfreeze by themselves since the aura will expire without someone having to use .unfreeze
- Make .freeze command usable with the following syntax:

      * .freeze (with a targeted player)
      * .freeze duration_in_seconds (with a targeted player)
      * .freeze playername duration (if duration is an invalid value it will be defaulted to the config one)
      * .freeze playername (in this case, duration will be defaulted to the config value)

- Make .listfreeze command able to show the remaining freeze duration on all affected players

Closes #12972
