feat: shredding option for .xlog and .snap deletion

Summary

1. Add a new option picodata run --shredding to enable shredding upon xlog_remove_file_impl.
2. For test purposes additionally use the inject_errors feature to keep files after shred operation and allow the test code to look inside and make sure that content was really shredded.
