Color Management: support different settings for render and compositing output

The Output Properties > Output panel now has a Color Management subpanel to
override scene settings. When set to Override instead of Follow Scene, there
are settings to:

* For OpenEXR, choose a (linear) colorspace for RGBA passes
* For other file formats, use different display/view/look/exposure/gamma

These settings affect animation render output, image save of renders and the
compositor file output node. Additionally, the image save operator and
compositor file output nodes also support overriding color management.

Includes some layout changes to the relevant panels to accomdate the new
settings and to improve consistency. Ideally subpanels would be used to better
organize these settings, however nodes and operators don't currently support
creating subpanels.
