TabBar: Initialize pinned tab width from real tab

Browse Source 
Calculates the padding between tab border and icon from tabRect
instead of using style pixel metric which was oftentimes incorrect.

Pinned tabs should now have correct size and icon be perfectly centered
with all possible widget and qss styles.
