gh-154987: Handle ValueError for drive-relative paths in tarfile filters

[zainnadeem786]

Summary

Fixes gh-154987.

On Windows, tarfile extraction filters use os.path.commonpath() to verify that extracted members remain inside the destination directory.

For drive-relative paths (for example Z:evil), ntpath.commonpath() raises ValueError because the paths are considered to be on different drives. That exception currently escapes instead of being translated into tarfile's existing structured extraction filter errors.

This PR catches that ValueError and treats those paths as outside the destination, preserving the existing extraction filter semantics.

Changes

• Handle ValueError raised by os.path.commonpath() during destination containment checks.
• Raise the existing:
  • OutsideDestinationError
  • LinkOutsideDestinationError
    instead of allowing a raw ValueError to escape.
• Add regression tests covering:
  • drive-relative member paths
  • drive-relative symlink targets
  • drive-relative hardlink targets
  • errorlevel=0 continuation behaviour

Testing

Executed:

PCbuild\amd64\python.exe -m test test_tarfile -m "*drive_relative*" -v

PCbuild\amd64\python.exe -m test test_tarfile \
    -m "*drive_relative*" \
    -m test_absolute \
    -m test_absolute_symlink \
    -m test_absolute_hardlink \
    -m test_link_at_destination \
    -m test_normpath_realpath_mismatch \
    -m test_errorlevel -v

All targeted regression tests passed successfully.
