Render xAxis annotations above yAxisLine

[envex]

What does this implement/fix?

We have to render one set of annotations above the other, so in some case an annotation line will render over the annotation tooltip. This is already how <BarChart /> works, the line charts were missed.

Until we can come up with a better solution to render the tooltips, we are going to prioritize rendering the xAxis annotations.
