Add function kunit_alloc_string_stream() to do a resource-managed
allocation of a string stream, and corresponding
kunit_free_string_stream() to free the resource-managed stream.
This is preparing for decoupling the string_stream
implementation from struct kunit, to reduce the amount of code
churn when that happens. Currently:
- kunit_alloc_string_stream() only calls alloc_string_stream().
- kunit_free_string_stream() takes a struct kunit* which
isn't used yet.
Callers of the old alloc_string_stream() and
string_stream_destroy() are all requesting a managed allocation
so have been changed to use the new functions.
alloc_string_stream() has been temporarily made static because
its current behavior has been replaced with
kunit_alloc_string_stream().
