Java: revert filtering of ancillary data extraction

[smowton]

This is because doing so presently breaks a code-scanning config that uses path-traversal sequences (. and ..) in its paths or paths-ignore directives, and the Java configuration is in traced mode (buildless would already have objected to these, since it uses resolve files which also doesn't tolerate them).

[Copilot]

Pull request overview

This PR reverts a previous feature that filtered ancillary data extraction for Java code scanning based on paths and paths-ignore settings. The revert is necessary because the filtering breaks code-scanning configurations that use path-traversal sequences (. and ..) in traced mode.

Key Changes

• Removes the change-notes documentation for the now-reverted feature
• Deletes the integration test suite that validated the path filtering behavior
• Removes all associated test data files (Java, XML, and configuration files)
