QQuickText{Edit,Input}: Reset selection when becoming readOnly.

When read only, controls may not be edited or altered, and indeed, a read-only
control cannot acquire a selection (as it cannot be interacted with).
Leaving an existing selection breaks that implication, so clear it when becoming
read-only.

[ChangeLog][QtQuick][TextEdit/TextInput] If a control has a selection, it is now
cleared when becoming read-only.
