pw_transfer: Use files in integration tests

This updates pw_transfer's integration tests to use local files as
transfer targets. This makes it simpler to coordinate between C++ and
Python and verify the results of transfer operations.

As part of this, a stream reader and writer that operate on files using
the C++ standard library are added to pw_stream.
