Find files only used only used/reachable from test files:
Added is_test_file property to WalkFileMetadata struct, generated during filewalk. Set to true if file matches pattern **/test/**.
Added property test_only_use to ExportedItemReport to identify items only imported by test files.
Added a second bfs walk on graph
First walk uses files from entry packages as initial frontier, generates the list and map of files not reachable and never-imported items.
Second walk uses test files as initial frontier.
After second walk we make a diff like processing, where we check for which files and items were initially marked as unused (not reachable by entry packages) and a second check (files and items marked as used after BFS on test files) to identify what is used only in tests.
