There are users find there is obviously memory leak with this feature.
In a inference, the memory increase 80M in one interact session (22s).
In workload test, 16GB GPU will be filled after about 2 hours.
It happens on oneAPI 2025.0- 2025.2.
Revert this PR since it includes big issue.
The issue is reported and the issue will be fixed in next official release.
After this feature is fixe in new SYCL version, this PR could be restored.
Here is the log in my test.
