libcamera: software_isp: Add member variables to track selected input/output pixelFormat

In order to have Debayer::start() tell the eGL shader compilation routine what
the input and output pixel format is, we need to have a copy of the
selected format available. Add variables to the inputConfig and
outputConfig structures to allow tracking of this data for later use.
