Android: Set EnterKeyNext as default type for QLineEdit

Behavior of EnterKey for virtual keyboard need to be changed for
QLineEdit. Before this commit, ImeOption was set to IME_ACTION_DONE.
Because of that, setting any text in QLineEdit automatically accept
QDialogs. That was annoying, when more than one QLineEdit need to be
set.

[ChangeLog][Widgets][Android] EnterKey type is now changed from
EnterKeyDefault to EnterKeyNext for virtual keyboard in QLineEdit. It is
done only if the focus can be moved to widget below.

Fixes: QTBUG-61652
