Add support for external language switch

Added new signal InputPanel::externalLanguageSwitch and
a property InputPanel::externalLanguageSwitchEnabled for
enabling external language switch.

If the externalLanguageSwitchEnabled is true, the signal is
triggered instead of built-in language popup.

The new language can be selected by setting the
VirtualKeyboardSettings::locale property.

[ChangeLog] Add option to use external language dialog instead of
built-in language popup.
