feat(dos): Allow to configure scan storage settings

Do not hard-code esp. `writeToStorage` to `false` as in the ORT server
use-case, where no ORT results files are used, scan results need to be
stored in order to pass them to other tools. Instead, take scan storage
settings from the `ScannerWrapperConfig`, like for the `FossId` scanner.
