libcamera: ipa: simple: Introduce a general correction matrix

Browse Source 
Let's introduce IPAActiveState::combinedMatrix that is separate from
IPAActiveState::ccm and represents the overall correction matrix, not
only the sensor colour correction matrix.

IPAActiveState::ccm still includes everything; this is changed in the
followup patch.
