Add the ability to control USM prefetch direction (host-to-device,
device-to-host) in the enqueue_function extension:
```cpp
sycl::ext::oneapi::experimental {
enum class prefetch_type { device, host };
void prefetch(sycl::queue q, void* ptr, size_t numBytes,
prefetch_type type = prefetch_type::device);
void prefetch(sycl::handler &h, void* ptr, size_t numBytes,
prefetch_type type = prefetch_type::device);
}
```
**Note:**
- ~~There is a test failure regarding a new ABI symbol: In order to not
break the ABI, I added a new handler function to represent prefetch from
device-to-host. Despite the precommit failures, this should not be an
ABI-breaking change and thus be okay to merge.~~ I modified the ABI
symbols tests as a part of this PR.
