Fix f16_sycl cpy call from Arc

[abhilash1910]

With respect to changes in #5289 , Arc has an issue for FP16 build when trying to query fp16_cpy on sycl . This is caused due to function arg mismatch , as it was calling an older version of the ggml_cpy_f32_f16_sycl method.

Error Log:

@airMeng @AidanBeltonS @NeoZhangJianyu @ggerganov please review . Thanks

LGTM, outside of my one comment. Thanks for catching this

[NeoZhangJianyu]

I suggest adding CI case with build for FP16:
update .github\workflows\build.xml to add build CI for FP16.

So that such break building for FP16 will be detected.

Thank you!
