Previously Handler was ignored - see

llvm/sycl/source/backend/level_zero.cpp

Lines 58 to 60 in 3ea29b2

	return detail::createSyclObjFromImpl<context>(
	std::make_shared<context_impl>(PiContext, detail::defaultAsyncHandler,
	Plugin, DeviceList, !KeepOwnership));

, this PR starts using it instead of defaultAsyncHandler.

Before this change, we were using async_handler from the TargetContext, see

llvm/sycl/source/backend/level_zero.cpp

Lines 70 to 72 in 3ea29b2

	return detail::make_queue(
	NativeHandle, IsImmCmdList, Context, &Device, KeepOwnership, Properties,
	ContextImpl->get_async_handler(), backend::ext_oneapi_level_zero);

. I'm updating to use the provided Handler, although I'm not sure about the consequences of that change. Regardless, using provided Handler instead of doing something completely different looks like a right thing to do for this interface.
