Fix T81842: Cloth brush not creating simulation areas for each tiling symmetry pass 

The cloth brush fixed simulation areas are created using the initial_location variable in the
 StrokeCache. This variable was not being updated by tiling symmetry, so all symmetry passes
were using the same simulation area location.
