pdfium: Fix inconsistent number of color components of ICC profile
fx_codec_icc.cpp specify default number of color components as 3 for unknown profiles. However, lcms may know such profile with different number of components. The inconsistency may lead to array access violation. This CL uses cmsChannelsOf() from lcms to ensure consistency. And rejects unexpected number according to PDF spec.
