Is your feature request related to a problem? Please describe.
I'm always frustrated when I need to show only the name or only the percentage label on VueUiDonut, but can't do so independently.

Describe the solution you'd like
Add a show property to style.chart.layout.labels.percentage and style.chart.layout.labels.name so each label can be toggled independently.

Describe alternatives you've considered
style.chart.layout.labels.dataLabels.show only toggles all labels at once, which is not flexible enough.
