report both conflicting packages

[SSE4]

if conan package has two conflicting dependencies, it outputs the following error message:

ERROR: Conflict in pcre/8.41@bincrafters/stable
    Requirement bzip2/1.0.8@conan/stable conflicts with already defined bzip2/1.0.6@conan/stable
    To change it, override it in your base requirements

in this case, the one is pcre/8.41@bincrafters/stable, which is using up-to-date version bzip2/1.0.8@conan/stable, but it's unclear which package is trying to use old version bzip2/1.0.6@conan/stable. it would be nice to output both conflicting package, otherwise it's hard to trace that error.
for the record, conan info doesn't work - it produces the same error message.

conan 1.18

This is being implemented in #5684, have a look at the proposed solution and comment there if you feel like the implementation is good enough, it needs more changes,....

Thanks @SylEze
