<AWT Dev> RFR: 8271603: Unnecessary Vector usage in java.desktop [v4]

[Andrey Turbanov]

> Usage of thread-safe collection `Vector` is unnecessary. It's recommended to use `ArrayList` if a thread-safe implementation is not needed. In post-BiasedLocking times, this is gets worse, as every access is synchronized.
> I checked only places where `Vector` was used as local variable.
