[SYCL] Add missing builtins for vec<X, 1>

[alexbatashev]

On host using builtins with vec<X, 1> types causes linkage errors. Add missing overloads.

Please add a trivial LIT test or extend some existing test.

Our current tests are not really scalable, and covering >500 builtins in one PR looks to much for me. Is it ok if I add a simple smoke test for now, and do a followup with better testing?

I think adding a simple smoke test is enough for LIT testing, we are not aiming to cover 100% of use cases with LIT tests.
Better testing can be provided by SYCL-CTS and/or separate test suite.

Then I’ll look into why CTS didn’t catch missing builtins.

The test needs minor fix in the compilation RUN line.

@v-klochkov I found even more missing builtins, and I believe some are still missing. I'll do a followup on adding the rest of them once proper testing is in place.
