Frameworks: fix navbar and pie icons for tablets and RTL

well due that we use a completly other attempt then googles navbar we do not
need to rely on different sized icons for portrait and landscape. So just a square
icon fits our needs perfect (which is so or so everwhere in AOSP default to use square ones).

Whatever recents pie feature showed us that we still forgot to size the pictures for our tablets
and as well for RTL user.

So let us do it now to fix any resizing issues on navbar and or SlimPie

Framworks: clean up the AOSP tablet icon mess

well.....on grouper the overlay size for the navbar is/was 56dp...so
google added bigger icons then the usual ones into the sw600dp folders.
Well newer tablets have 48dp as default like the phones so the slightly bigger
icons do not fit 100% correct. It is not much but it is noticable.

So all devices have same navbar default height...so all icons should have same size
as well. Just remove the overlay icons so that the system automatically chooses the right
one from the default screen qualifier.
