[improvement](statistics)Remove useless stats validation check. (#43279)

Remove useless stats validation check.
Before, we will not load the column stats when table rowCount > 0 and
ndv == 0 and nullCount != rowCount. This is to avoid using invalid
stats.
Now, we remove this validation because the planner side added validation
to the column stats, (see #41790).
Besides, after remove of the validation, it is easier to add regression
test using stats injection.
