[SYCL] Include sycl/builtins.hpp in imf header (#7858)

sycl math functions are used in util functions in intel math headers to
provide equivalent functionalities as CUDA math. We missed including
sycl/builtins.hpp previously, so users must include sycl/sycl.hpp before
including sycl intel math headers, this pr fixes this issue.
