Respect specified minimum height for menuBar also if it has HFW.

Browse Source 
If the menu bar is subject to height for width (HFW) we should of
course respect that, but in addition we should ensure that the HFW is
within the minimum and maximum height. This also is consistent with how
QGridLayout calculates the effective minimum row height.

This fixes a regression because change 4780f94e391b5e881497c5228661dead
turned QTabWidget into a proper height-for-width citizen, and when
setting a QTabWidget as a menuwidget, the buggy codepath for HFW was
suddenly hit in menuBarHeightForWidth().

Task-number: QTBUG-31057
