Color management cleanup and improvements

- De-duplicate code used by color management panel drawing,
  moved this panel to utility file in bl_ui

- Added support of per-window color management control
  which means view transform. exposure and gamma could be
  set per window and all spaces would use this settings.

  This is default behavior for older files now.

- Added support of color management display of movie clips
  in clip editor.

  Supported both texture buffer and fallback draw methods.

- Fixed default values for exposure and gamma
