Refactor: Condition.apply needs a GameEvent parameter

[Alex-Vasile]

Cards like [[Resourceful Defense]] have an intervening if-clause which needs to look at the permanent that is leaving the battlefield in order to verify if the condition for the triggered ability is met.

As currentling implemented Condition's .apply() only takes in a Game parameter, and I don't see how to get access to the event information which is causing the condition to go off. GameState has a simultaneousEvents variable which would store the events, but it's cleared before each event is individually handled: https://github.com/magefree/mage/blob/94dc91d8e19a395770b091e87d9e2c79260d09b8/Mage/src/main/java/mage/game/GameState.java#L783-L795

The current alternative is to create a custom triggered ability, e.g. [[The Ozolith]]: https://github.com/magefree/mage/blob/f6be167aeb0fa61840f4efa893d901bf80039be6/Mage.Sets/src/mage/cards/t/TheOzolith.java#L61-L94

These kinds of implementations could be simplified to use common abilities if the Condition has a was of looking at the event that is setting off the triggered ability.
