* 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

as far as i could tell this cast is unneeded because [GDBStub::SetServerPort](https://github.com/citra-emu/citra/blob/master/src/core/gdbstub/gdbstub.cpp#L897) takes a u16 and [values.gdbstub_port](https://github.com/citra-emu/citra/blob/master/src/core/settings.h#L116) is already a u16

* Removes circular dependences (common should not depend on core)

* implement frame limiter

* fixes

Allows users to choose a single screen layout or a large screen layout.
Adds a configuration option to change the prominent screen.

This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.

Uses QSettings on citra-qt, and inih on citra-cli.
