fix focus: 'self' not work when item emphasis by other component

Fixed issues

Fix #18475

Details

Before: What was the problem?

When axisPointer is set to axis or line, the elements in the chart will be triggered to be highlighted and the __highByOuter property on the elements will be marked to indicate that they are currently highlighted,

but when emphasis.focus = 'self' is also set, it will enter blurSeries logic, where all the elements in the chart will be forced to blur

and then go to enterEmphasisWhenMouseOver, where the element with focus:'self' will be highlighted

But since the element has already been highlighted by axisPointer, __highByOuter is no longer the value of falsy, and in this method it determines whether this property is falsy, and if so, it goes to the highlighting of the node.

Obviously, in this case, the node that should have been highlighted is first blurred, and then the highlighting logic is skipped

After: How does it behave after the fixing?

I'm not quite sure why I'm adding the node __highByOuter to be falsy here as a basis for continuing to highlight or not

So in the blurSeries method, if a series is focus self and is a highlighted trigger series, if there are elements in the series that have been marked __highByOuter by another z component, then that element will be skipped blur
