[LyX/master] Replace Q_WS_WIN with appropriate guards to account for Qt5.

commit 4521fc757ba5906402e2e46b23b47dfc7f436675

    Replace Q_WS_WIN with appropriate guards to account for Qt5.
    
    This commit replaces almost all occurrences of Q_WS_WIN to comply
    with Qt5. The remaining occurrences should *not* be replaced,
    because the guarded code won't compile on Qt5.
