What does this PR do?

fix zero data in pictorialbar can't render correct, when the borderWidth be setted.

Fixed issues

• 使用pictorialBar，symbolOffset: [0, '-50%'], 当data中第一个值为0的时候，位置出现偏差，显示在左上角 #12789

Details

Before: What was the problem?

I'm not exactly sure what pxSign really means, but it looks like a direction.
when data is zero, then boundingLength is zero, pxSign will be zero, and then symbolScale will be zero too, and if borderWidth setted and not zero, the valueLineWidth will be NaN.

After: How is it fixed in this PR?

pxSign will be part of the denominator somewhere else, so it shouldn't be 0
