[SYCL][HIP] Expect failure of some tests that have 'has(aspect::atomic64)' (#861)

Expect failure of some tests that have 'has(aspect::atomic64)' because hip backend does not have such check implementation.
PR with specialization removing for atomic64 check: intel/llvm#5430
Github issue for implementating such check on hip backend: intel/llvm#5570
**Should be merged at the same time with mentioned [PR](intel/llvm#5430
