[hip][SYCL] Implement "case PI_DEVICE_INFO_ATOMIC_64" check on hip backend.

[denis-kabanov]

The case for PI_DEVICE_INFO_ATOMIC_64 is currently not implemented in sycl/plugins/hip/pi_hip.cpp, so get_device_info receives PI_INVALID_VALUE. But without the 'template <> struct get_device_info<bool, info::device::atomic64>' specialization from sycl/source/detail/device_info.hpp (this specialization is planned to be removed), PI_INVALID_VALUE will cause some tests to fail.

Does PI_DEVICE_INFO_ATOMIC_64 mean atomic operations over both global and shared memory ?

[denis-kabanov]

As I know, the PI_DEVICE_INFO_ATOMIC_64 case should checks that kernels submitted to the device may perform 64-bit atomic operations. (e.g. device.has(aspect::atomic64) == 1 if the device supports 64-bit atomic operations)

Closing this as it was implemented in #6429, feel free to re-open if the issue persists.
