Core/Conditions: Added CONDITION_SOURCE_TYPE_PLAYER_CONDITION

[meji46]

Changes proposed:

• Added CONDITION_SOURCE_TYPE_PLAYER_CONDITION (can be used for serverside playerconditions referenced by vendors or gameobjects)
• Update GO dynamic flags according to player conditions (serverside playercondition always returns true if it isn't conditioned)
• Fixed dynamic flags logic for GAMEOBJECT_TYPE_GOOBER
• Implemented dynamic flags logic for GAMEOBJECT_TYPE_BUTTON

Issues addressed:
Maybe closes #27374

Tests performed:
Builds, tested in-game.
Examples:

DELETE FROM `conditions` WHERE `SourceTypeOrReferenceId`=34 AND `SourceEntry` IN (9766, 10282, 10355);
INSERT INTO `conditions` (`SourceTypeOrReferenceId`, `SourceGroup`, `SourceEntry`, `SourceId`, `ElseGroup`, `ConditionTypeOrReference`, `ConditionTarget`, `ConditionValue1`, `ConditionValue2`, `ConditionValue3`, `ConditionStringValue1`, `NegativeCondition`, `ErrorType`, `ErrorTextId`, `ScriptName`, `Comment`) VALUES
(34, 0, 10355, 0, 0, 47, 0, 26955, 8, 0, '', 0, 0, 0, '', 'Satisfy player condition if quest 26955 is taken'),
(34, 0, 10282, 0, 0, 47, 0, 5581, 8, 0, '', 0, 0, 0, '', 'Satisfy player condition if quest 5581 is taken'),
(34, 0, 10282, 0, 1, 47, 0, 14374, 8, 0, '', 0, 0, 0, '', 'Satisfy player condition if quest 14374 is taken'),
(34, 0, 9766, 0, 0, 47, 0, 25731, 8, 0, '', 0, 0, 0, '', 'Satisfy player condition if quest 25731 is taken');

Known issues and TODO list: (add/remove lines as needed)

• We need to prevent a player condition from being conditioned by itself (CONDITION_PLAYER_CONDITION) or prevent circular references (player condition A conditioned by player condition B - player condition B conditioned by player condition A).
  • Make source type CONDITION_SOURCE_TYPE_PLAYER_CONDITION incompatible with CONDITION_PLAYER_CONDITION or
  • Restrict CONDITION_SOURCE_TYPE_PLAYER_CONDITION to serverside player conditions (CONDITION_PLAYER_CONDITION can only reference db2 data)
