framebuffer_layout.cpp mini refactor (#7300)

Browse Source 
* framebuffer_layout.cpp: simplify FrameLayoutFromResolutionScale

- upright_screen seems to only be swapped width and height calculation, so it is replaced with std::swap
- Get rid of call to GetCardboardSettings, The FrameLayoutFromResolutionScale function is used for Screenshots and Video Dumping where we dont need 3D effects

* framebuffer_layout.cpp: Combine SideFrameLayout and MobileLandscapeFrameLayout into variants of LargeFrameLayout

* framebuffer_layout.{cpp,h}: rename maxRectangle to MaxRectangle, plus

minor documentation update

* clang-format
