Related-To: NEO-6075 After this change driver will fail clBuildProgram/zeModuleCreate api calls whenever stateful access is discovered on PVC. This is required since in this case allocation greater than 4GB will not work. If user still wants to use stateful addressing mode, -cl-opt-smaller-than-4GB-buffers-only / -ze-opt-smaller-than-4GB-buffers-only build option should be passed as build option, but then user can not use bufers greater than 4GB.
