After intel#1770 some uses of associateWithHandler have to be guarded by "#ifndef __SYCL_DEVICE_ONLY__" as the accessor's inheritance chain differs between host/device compilation. Put the burden of that into the handler's implementation instead of paying the price at uses.

Minor readability improvement: when there is an else branch, it's better to avoid negation. I.e. prefer
#ifdef
X
#else
Y
#endifto
#ifndef
Y
#else
X
#endif

Usually, I would have done that already. However, in cases when one branch is much more important/interesting than the other, the decision isn't so clear. Also, pre-existing usage of this in the file (beyond the affected lines) is such that the order is determined by what code it is (host - host is the first condition, device, inside parallel_for - device is the first condition), so I'm not sure if that's a positive change.
Anyway, I'm committed the suggested change. CodeOwners are free to either merge it or revert and merge the previous version.
