Refactoring event click-drag detection broke click detection for simulated events. Resolve this by sharing logic for update previous values in `wmWindow.eventstate` for regular event handling (no functional changes for non-simulated events). Failure to detect clicks for simulated events broke the undo test `test_undo.view3d_multi_mode_select` in `../lib/tests/ui_simulate/run.py`. All undo tests now pass.
