(1) Some refactor about axisTick, axisLabel, splitLine, splitArea interval logic: arrange and uniform the API, about 'ifIgnoreOnTick', 'isLabelIgnored', 'getTicksCoords',  'getLabelsCoords', etc. Fixed the inconsistent calling of user specified "axis interval" function.
(2) Make the choice of axisTick, axisLabel, splitLine, splitArea be stable when category axis auto interval exists and moving by dataZoom.
(3) Make the animation appropriate for label, ticks, splitLine, splitArea when view window moving (by dataZoom) in category axis.
