### Steps to Reproduce

1. Create a chart with data with seconds timesteps with a year overlap (see reproduction snippet link)
2. Load the chart / play with the slider.
3.

### Current Behavior

💥 the chart is very laggy even on little data.

### Expected Behavior

The chart loading should be smooth.

### Environment

```markdown

### Any additional comments?

I have run some investigations and I think there are 2 main issues.
The first one lies [here](https://github.com/apache/echarts/blob/d4ce746cd8e8663659cf3063c5b509e0b9d0de40/src/scale/Time.ts#L566). `setMethodName` can be very costly as we can see in the flame graph. My suggestion would be to update this function to take the `unitName` as a parameter and to compute the intervals with something like:
```javascript
function getUnitStep(unitName: TimeUnit): number {
// Only return a step for units with fixed millisecond values.
// 'month' and 'year' have variable lengths and should not be handled here.
const step = ({
'week': ONE_DAY * 7,
'half-year': ONE_YEAR / 2,
'quarter': ONE_DAY * 95,
'half-week': ONE_DAY * 7 / 2,
'day': ONE_DAY,
'half-day': ONE_DAY / 2,
'quarter-day': ONE_DAY / 4,
'hour': ONE_HOUR,
'minute': ONE_MINUTE,
'second': ONE_SECOND,
// 'month' and 'year' have variable lengths and should not be handled here.
'year': ONE_YEAR,
'month': ONE_DAY * 31, // Approximate value for month
'millisecond': 1
})[unitName];

return step;
}

function addTicksInSpan(
interval: number,
minTimestamp: number, maxTimestamp: number,
getMethodName: string,
setMethodName: string,
isDate: boolean,
out: InnerTimeTick[],
unitName: TimeUnit
) {
const step = getUnitStep(unitName);
let dateTime = minTimestamp;
while (dateTime < maxTimestamp && dateTime <= extent[1]) {
out.push({
value: dateTime
});
dateTime += step * interval;
}
out.push({
value: dateTime,
notAdd: true
});
// ......
}
```

Secondly, I am under the feeling that we are iterating a bit too much in this function based on a few console.log experiments but this might be me not understanding the full logic behind this piece of code
