开启自动旋转时, 如果文本对齐方式是右对齐, label 会遮挡

```ts
xAxis: {
label: {
autoRotate: true,
style: {
textAlign: 'right'
// textAlign: 'center'
// textAlign: 'left'
},
formatter: () => "asfkdsajfksdfjsdkjfsd"
},
}
```

* **G2Plot Version**:
* **Platform**:

Start by reproducing the issue in the linked G2Plot CodeSandbox using an xAxis label with autoRotate enabled, textAlign set to right, and the shown formatter. Trace the axis-label rendering entry point to find why the rotated label is obscured, then verify that right-, center-, and left-aligned labels render without overlap.
