QS: fix wrong measurement on 4 or 5 tiles per row on settingspanelview

Issue was only visible on devices which have settingspanelview (tablets - not flippable)
on boot up on landscape and had 4 or 5 tiles per row set. Problem is that due we have
the same layout situation like in portrait on this devices that the layoutparameter
height needs to be calculated in landscape as well.

Solve it with forcing (on only settingspanelview devices) the calculation on landscape
as well

fb: make QS again rtl aware

we removed on first version the possibility to respect rtl
add it back to be aware.

As well remove the try to fix the tablet on first boot landscape problem
It actually did not fix the problem.

QS: no need to rebuild the complete QS on orientationchange

to update just the layout parameter from the container view
is more then enough

As well after theme change we can directly return due that
all gets rebuilded
