Subject: Material: calculate BusyIndicator's line width

A BusyIndicator with its default implicit size (48px) gets the same
line-width (4px) as before: 48px / 12 = 4px. The line-width is still
not adjustable as requested in QTBUG-64872, but tiny and huge busy
indicators look now much better.

Task-number: QTBUG-64872
