Provide in ORT a (FossID) snippet report

[nnobelis]

#6791 added support for snippets findings to ORT model.

Currently, no ORT report presents these findings.

A report showing these results needs to be added to ORT.
Unfortunately, there are scanner-specific limitations.
For FossID for instance:

• FossID snippet results don't contain matching lines information due to performance issues (See FossID API for matched line needs to be improved #7028)
• Current information available in the model does not fully cover the UI of FossID when presenting the snippets:
  

Indeed our goal at Bosch is to provide a rich report in ORT that would contain all FossID-available data, but also discards the need of FossID UI when writing snippet curations/choices.
To achieve this, new FossID-specific fields of the snippet would need to be added to the ORT model, in a generic way. See #7022 for the preliminary work.
Then during report generation, the (costly) matched lines information could be fetched.

Here is an early prototype how such a report would look like :

Please note our current prototype generates an html report instead to be able to leverage Collapsible blocks of AsciiDoc : such blocks could be useful for e.g. "how to fix hints" for the snippet curations/choices.

Last comment: while it would be great to have a snipped report that support both FossID and ScanOSS findings, I fear that the implementation would be too complex due to Scanner-specific findings.
Therefore I would focus on creating one Reporter per scanner.

@nnobelis can this be closed due to the work done in #7127?

Closed with #7127.
