Color management: added view transforms form nuke-default and spi-vfx

- Added some extra view transforms to play with. It's not absolutely
correct in terms this views were changed to use aces space as input.
This gives exactly the same result as if using stand-alone spi-vfx
and nuke-default configuration, but for real merge of this configs
it'll be needed to add extra input spaces and transformations between
them.

- Replaced hard-coded aces input color space with default ocio
linear space which makes it easier to play with different
configurations.

- Fixed SCons installation of color management configuration which
used to skip copying LUTs when there was "luts" folder in install
destination.

- Print whether OCIO was enabled when building with CMake.
Could be helpful due to OCIO is being automatically disabled
if needed libraries are missed.
