[SYCL] Make internal function to be static in imf rounding utils (#15548)

jinge90 · web-flow · commit c7c4130c0c70 · 2024-10-08T10:06:10.000+02:00
The internal util functions "get_grs_bits" used by rounding mode related
functions for both fp32 and fp64 should be marked as static, otherwise
linker will report multiple definition error when developers use fp32
and fp64 intel math function in the same compiling unit.
