[SYCL] Use inline in device definition of _invalid_parameter

[ianayl]

Header definitions should be inline to avoid multiple definitions error.

I thought this version doesn't help with the error downstream... Ian, can you confirm it's fixed?

@aelovikov-intel This was the version that fixed the downstream kmeans build failures, I later realized me not being able to replicate was because of my environment.

I am testing to see if this'll also fix post commit: https://github.com/intel/llvm/actions/runs/15026620724
