[lldb] Use PyBytes and PyByteArray in Python Data Objects unittest (#82098)
Use a Python Bytes and ByteArray object instead of Integers for
TestOwnedReferences and TestBorrowedReferences. These two tests were
failing when building against Python 3.12 because these Integer objects
had a refcount of 4294967296 (-1). I didn't dig into it, but I suspect
the Python runtime has adopted an optimization to decrease refcounting
traffic for these simple objects.
