Fix the appearance of QSpinBox arrows on high-DPI displays

Browse Source 
A previous change to QLineEdit::sizeHint() has caused the QSpinBox
arrows to break the widget frame on a high-DPI display with some
particular scale values like 150 or 175%. This change updates
QLineEdit::sizeHint() so that it has a minimum height, using the same
values used in 5.11.

Fixes: QTBUG-76047
