Color Management: Use OCIO's built-in function for sRGB color space

Use OCIO's built-in functionality for sRGB which allows to have un-clipped
range of the input colors. The lookup tables are now removed.

Should be no functional changes on the user side.
However, it is possible that this change does not preserve exact per-pixel
value due to difference in precision.
