M68: Better determine if ICC colorspaces can be used for blending.

Implement CPDF_ColorSpace::IsNormal() and check it when rendering. While
IsNormal() is trivial for most colorspaces, it needs to be implemented
separately for ICC colorspaces.

This fixes a rendering regression from commit 1c0de38c.
