minghong 3fc8c19735 [improve](nereids)compute statsRange.length() according to the column datatype (#18331 )

we map date/datetime/V2 to double. this map reserves date order, but it does not reserve range length.
For example, from 1990-01-01 to 1991-01-01, there are 12 months. for filter `A < 1990-02-01`, the selectivity
should be `1/12`.

if we compute this filter by their corresponding double value,
`sel = (19900201 - 19900101) / (19910101 - 19900101) = 100/10000 = 1/100`

the error is about 10 times.
This pr aims to fix this error.
Describe your changes.

Solution:
convert double to its corresponding dataType(date/datev2), then compute the range length with respect to its datatype.
