有计划支持图形(文本等其他元素也算)层叠顺序的控制吗？ #3757

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

背景：需要灵活设置X轴标签位置，当标签设置在图形内时，标签会被图形覆盖（如下图） 对应配置：

import { Chart } from '@antv/g2';

const data = [
  { year: '1991', value: 3 },
  { year: '1992', value: 4 },
  { year: '1993', value: 3.5 },
  { year: '1994', value: 5 },
  { year: '1995', value: 4.9 },
];
const chart = new Chart({
  container: 'container',
  autoFit: true,
  height: 500,
});

chart.data(data);
chart.tooltip({
  showMarkers: false
});

chart
  .interval()
  .position('year*value')
  .color('year');

// 设置X轴位置偏移
chart.axis('year',{
  label:{
    offset: -15,
    style:{
      fill: '#000'
    },
  },
})

chart.interaction('element-highlight');
chart.interaction('element-list-highlight');
chart.interaction('legend-highlight');
chart.interaction('axis-label-highlight');

chart.render();

期望解决方案：提供控制层叠循序的配置

What does the proposed API look like?
