[SYCL][HIP] add missing nearbyint and rint (#16373)

Failed to compile OneDNN using DPCPP on AMD with sycl because the code
[here](https://github.com/oneapi-src/oneDNN/blob/c852fdc60073a1ae298618c4faf26487b4144755/src/gpu/generic/sycl/eltwise_kernels.hpp#L137)
that will run on the device actually calls `nearbyintf`
[here](https://github.com/oneapi-src/oneDNN/blob/c852fdc60073a1ae298618c4faf26487b4144755/src/common/math_utils.hpp#L120-L131)
, but `nearbyintf` lacks a symbolic definition.
Same solution as #11177 but go
straight to the `__ocml` symbols
