RFR: 8150564: Migrate useful ExtendedRobot methods into awt.Robot [v5]

[Damon Nguyen]

> Some useful methods (click, glide, waitForIdle, type) in ExtendedRobot should be migrated into Robot itself so that ExtendedRobot can be removed in the future. The tests using these ExtendedRobot methods will be handled separately.
