Print the "compound-build-tracer.log" in debug mode

[aibaars]

In analyze-action.ts: L110 we print the per language log files from the database log folders. However, we don't print the multi-language tracer log (ie. a file named compound-build-tracer.log) which is important for debugging tracer related issues. The build-tracer.log files in the per language database folders are actually useless because they are virtually empty and contain only the log of the codeql trace-command runs by the codeql-action/init steps for probing the tracer related environment variables.
