perf(ivy): improve NaN checks in change detection (#32212)

This commit drops our custom, change-detection specific, equality comparison util
in favour of the standard Object.is which has desired semantics.

There are multiple advantages of this approach:
- less code to maintain on our end;
- avoid NaN checks if both values are equal;
- re-write NaN checks so we don't trigger V8 deoptimizations.
