17207: Alt+F4 to close a dialog should not activate the top menu

[krasko78]

Resolves: #17207

The main menu is activated on the release of the Alt key when m_needActivateHighlight is true. m_needActivateHighlight should become true only when the Alt key is previously pressed alone and not in any other case. On the other hand, it should be set to false as soon as a menu is highlighted, navigation started, another key is pressed and when the menu is closed.

@Eism @DmitryArefiev @zacjansheski I think this one can be tested?

All seems to be fine. I only found that Edit menu button is slightly highlighted but it's minor and probably not related to the current PR

@krasko78 Can you rebase please? (I want to recheck it with latest changes)

@DmitryArefiev Rebased. I've seen this issue with the Edit menu highlight in other areas of MuseScore, e.g. in the official 4.4.4 release open the Parts dialog and press ESC. Or open the properties of a palette cell and press ESC (highlights the File menu instead). Might be a Qt bug.
