RFR: 8314754: Minor ticks are not getting updated both the axes in LineChart

[Markus Mack]

This PR ensures the `tickMarksUpdated()` method (overriden with minor tick mark layout code in subclasses) is called during `Chart` `Axis` layout when needed.
Previously, it was only called when tick mark length or range was changed, which is not happening during axis animations, causing minor ticks to become outdated when animations are enabled.

I've added a test that fails with the previous code, specifically checking the tick mark spacing.
Alternatively the test could be implemented by accessing ValueAxis.minorTickMarkValues, which would need to be made at least package-private however (with a shim). This implementation checks the tick mark `Path` shape instead, which is already publicly accessible (but could be considered an implementation detail).
