Qt namespace: add a Qt 7 note about enumerator order

LayoutDirectionAuto is the default in qguiapplication.cpp's
layout_direction. Because the numeric value isn't zero, it forces the
variable into the DATA segment instead of the more efficient BSS one.

At a less technical level, LayoutDirection{} should really produce the
default, Auto, instead of LeftToRight. APIs have been changed for
lesser violations of inclusivity :)
