SidebySide Layout (#2859)

Browse source 
* added a SidebySide Layout

* Reworked, so both screen have the same height and cleaned up screen translates.

* added the option in the UI, hope this is the right way to do it. formated framebuffer_layout.cpp

* delete the x64 files

* deleted ui_configure_graphics.h

* added Option for the Layout in the xml

* got rid of SIDE_BY_SIDE_ASPECT_RATIO because it was useless. pulled translate into variables

* changed shift variables to u32 and moved them in their respective branch. remove notr="true" for the Screen layout drop down

* reworked intends :). changed function description for SideFrameLayout

* some description reworking
