simpleperf: keep binaries for debugging failed unwinding cases.
We need binaries for debugging failed unwinding cases. So
change --keep-failed-unwinding-stack-data to
--keep-failed-unwinding-debug-info, which stores both stack data and
used binaries for failed unwinding cases.
To store binaries in perf.data:
1. Add debug_unwind feature section to keep binary path and size info.
2. Add debug_unwind_file feature section to keep binary data.
