RFR: 8172849: Non-intuitive baseline alignment for labeled controls with graphics [v2]

[Karthik P K]

> Issue was observed because even when graphic height was less than text height of the Label, graphic height was considered while calculating the baseline offset. This was shifting the baseline offset and resulted in misalignment.
> 
> Updated `computeBaselineOffset` to exclude graphic height from baseline offset calculation when graphic height is more than text height.
> 
> Added unit test to validate the fix.
