<Swing Dev> RFR: 4710675: JTextArea.setComponentOrientation does not work with correct timing [v2]

[Prasanta Sadhukhan]

> It is seen JTextArea.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT) orientation is not honoured if it is called after setText() and remain at LTR orientation. It changes the orientation only if some more text is typed additionally to existing text.
> This behaviour is different from JTextField where the RTL orientation is honoured from start.
> Proposed fix is to check for ComponentOrientation propertyChange event and set i18n property if it is not set, so that orientation is honoured as soon as setComponentOrientation() is called.
> Checked for all L&Fs in all supported platforms.
