Updated the arena crowd manager to turn off overlaps

Added a cheat to the cheat manager to toggle arena crowd visibility

Added a cheat to deactivate the endless spawning

Finally found a workaround for the play tagged dialogue requiring a hard npc ref

Reduced hard refs on the base object and took it from 3126 asset refs and 187mb to 491 asset refs and 12.4mb!!!

Solved the perf issue on 5.7 with the new openxr space warp
