[SYCL] fix comparator to be strictly less-than. (#8259)

the comparator to sort should be strictly less than, rather than lazy
boolean check.
On Windows, a debug build may insert a check to make sure that
comparator(a,b) != comparator(b,a) and this check results in an assert
when tested on the current boolean check
