AI Target Unit for Direct vs Arc Attack (0019cd9c)

BATTLE.BIN :  - AI_Target_Unit_for_Direct_vs_Arc_Attack_(0019cd9c)
Ability simulation from a given position : handle Targeting and outcome. Test all targetable tiles, compare priority score, keep the best in AI 0x34 Table
------------------------------------------------------------------------------------------
Parameter : Nothing
Return : r2 = 0x00 Default result / No tiles to Target ( Set_Target_Tiles ) / AI 0x19bc = 0x00 (after checking priority)
         r2 = -0x01 if VSync_call returns r2 > 0x1b8
         r2 = -0x01 if Check_Set_Highest_Unit_Priority_(0019d308) returns r2 -0x01
