Revert "[FEATURE]Check date type to avoid scan all partitions"

Reverts #4756

This commit has some problem when handling predicate like:
k1 = "2020-10-10 10:00:00.000"

This is a valid predicate, and FE Datetime can not support milli or micro seconds, so it will treat it as invalid date time value.

So we revert it, and may find some better solution later.
