QComboBox: add property placeholderText
QComboBox had no option to tell the user that he must select an item -
there was no placeholder text like e.g. in QLineEdit. This feature is
widely used in html forms so we should support it also.
Therefore add a new property 'placeholderText' to specify a text which
should be shown when the current selected index is invalid.
[ChangeLog][QtWidgets][QComboBox] QComboBox got a new property
'placeholderText'
