9402e082 - [SYCL] Replace __clc_native_exp2/tanh with nv functions in SYCL headers (#21472)

[SYCL] Replace __clc_native_exp2/tanh with nv functions in SYCL headers (#21472) Why: - __clc_* names are libclc-internal conventions and are confusing in SYCL headers. - After this change, clc-remangler don't need to handle __clc_* symbols.
