[Metric] Improve title/subtitle/extra visibility breakpoint based on fit font size

[markov00]

Based on this discussion #2548 (comment)
We probably could improve the elementVisibility breakpoits based on the new default calculations.
Currently we do the following:

• first we compute the heightBasedFontSizes and the element visibility for title/subtitle/extra/value based only on height (with getMetricTextPartDimensions)
• then we compute the fit fontsize for the value (with getFitValueFontSize)
• and then we update the calculated value font size based on the desired configuration (fit, default/snap)

We can probably change this to compute the element visibility after that to increase the visibility of more text as possible
