RFR: 8233477: : [Win LAF]The tooltip doesn't display correctly in Win LAF [v2]

[Tejesh R]

> The tooltip displays accelerated string along with the toooltip string. The feature is implemented and applicable for Metal Look and Feel only. Hence the test is updated for Metal Look and Feel by hard wiring it in the code. Updated the test from manual to automatic.

Tejesh R has updated the pull request incrementally with one additional commit since the last revision:

  Removed unused parameter isTooltipAdded
