[CE] Extract transform computation logic to ProjectionSpace
The logic that computes the transformation matrix that maps
from one projection space to another currently lives in
DisplayDevice::setProjection although it's not specific to
the DisplayDevice. In this CL we move this to ProjectionSpace
so it can be reused and add appropriate testing. Additionally
we move most of the remaining logic from DisplayDevice::setProjection
to Output::setProjection.
