[SYCL] Avoid copying of NormalizedKernelFunc temporary (#11368)

Coverity analysis of
[IntelPython/dpctl.git](https://github.com/IntelPython/dpctl) SYCL-based
projects shows 6721 hits of COPY_INSTEAD_OF_MOVE type issues in
ResetHostKernelHelper with the suggestion to use
std::move(NormalizedKernelFunc) instead.
