This commit adds the "Save as Render" feature to the file output node,
that allows to disable the application of the configured view transform
and other color management settings on the image. If disable it uses
the standard view transform instead. This feature was originally
suggested in T83842 and is part of the color management improvements
task in T68926. With this feature it is possible to toggle the
application of the color management settings for each input socket
of the File Output node individually.
