[issue42095] plistlib: Add tests that compare with plutil(1)

[Ronald Oussoren]

New submission from Ronald Oussoren <ronaldoussoren at mac.com>:

plistlib is a library that reads and writes files that should be compatible with Apple tooling/libraries.

Add some tests that verify interop (when ran on macOS):
- Generate plist files with plistlib and parse with plutil
- Generate plist files with plutil and parse with plistlib

Do this both for xml and binary plist files.
