<i18n dev> RFR: 8324491: Keyboard layout did not keep it state if it was changed when dialog is active

[Dmitry Markov]

If AWT/Swing app displays several windows and an user changes the keyboard layout and then closes the focused window, the app does not keep the keyboard layout changes.

It is necessary to sync currentLocale and Windows keyboard layout values in `WInputMethod` class before component activation.
