[fix](nereids) fix comparison with date like (#45735)
### What problem does this PR solve? Issue Number: close #xxx Related PR: #45382 Problem Summary: #45382 had fix compare date/datev1 with datetime literal wrong cutting. but it not fix completely. ``` if (right instanceof DateTimeLiteral) { DateTimeLiteral dateTimeLiteral = (DateTimeLiteral) right; right = migrateToDateV2(dateTimeLiteral); if (dateTimeLiteral.getHour() != 0 || dateTimeLiteral.getMinute() != 0 || dateTimeLiteral.getSecond() != 0) { ... } } ``` For the above code, if check right is date time literal, but notice that datetimev2 literal is datetime literal's child class. so datetimev2 literal will also run the above code. And datetimev2 literal should check its microseconds not equals to 0. for example: `date_a = '2020-01-01 00:00:00.01'` should opt as `FALSE`, but not `date_a = '2020-01-01'`.
