[Lazarus] AutoAdjustLayout fixes

[Alexey]

Juha,
I tried to improv http://mantis.freepascal.org/view.php?id=30995
and i tried other LCL controls which need this too. 
SpinEdit/FloatSpinedit/Check/Radiobtn/Group/Panel..
now i see that no more fixes needed.
SpinEdit's are childs of TCustomEdit--so they ok today.
Others dont need work: they autosize in x/y and so this work (for one 
line edits) not needed for em.
AutoSize scaling _overworks_ AutoAdjust scaling.
So AutoAdjust scaling can ignore other AutoSize ctrls.

(tested on app)
