The SBOM functions so far had a lot of Qt-specific logic inside them. Decouple this logic into separate Qt-specific functions or explicitly guard the code with Qt-specific handling options, to prepare for a cleaner SBOM public API. The generic functions then call the Qt-specific ones if various internal options are set. This approach is used, rather than directly passing values to the generic functions because: - we have cases where we need to recursively pass the values all the way down to all recursively created attribution targets - some of the logic needs to know about values before and after qt processing, and this could be achieved with something like lambdas but it's not worth the complexity Pick-to: 6.8 6.9 Task-number: QTBUG-122899 Change-Id: I4399c41f4d976f20b16a0bb0c674d4f07ee1ccd4 Reviewed-by: Joerg Bornemann <joerg.bornemann@qt.io>
