`olShutDown` was not properly calling deinit on the platforms, resulting in random segfaults on AMD devices. As part of this, `olInit` and `olShutDown` now alloc and free the offload context rather than it being static. This allows `olShutDown` to be called within a destructor of a static object (like the tests do) without having to worry about destructor ordering.
