[SYCL] Add removal guard for info::device::atomic64 use-cases

[Robertkq]

Fixes issue #14920

This PR guards all info::device::atomic64 related code in include guards for breaking changes.

I have manually tested a sample app that was querying for this info, providing the -fpreview-breaking-changes compile flag to it is now failing with the follow error:

simple-sycl-app.cpp:48:55: error: no member named 'atomic64' in namespace 'sycl::info::device'
   48 |   if (Queue.get_device().get_info<sycl::info::device::atomic64>()) {
      |                                                       ^~~~~~~~
1 error generated.

Which I think is the expected result for the next major release.
