qcacmn: Remove qdf libc implementations

The libc implementations of QDF were originally intended to be used for
off-target unit testing purposes. However, doing this involved
reimplementing large sections of QDF. Instead, unit testing is being
done in an emulator, which provides many of the benefits of off-target
testing without needing to reimplement any logic. As such, remove the
libc folder from QDF.
