fix: (1) Fix: fix bar overflow issue on category axis with boundaryGap: false - use the newly added containShape handler. (2) Fix regression: Drop the previous containShape strategy on bar series, use a simple strategy for better compatibility. (3) Fix regression: Fix new added bar clip feature on single data item case. (4) Fix regression: Clarify code.
