sql: forbid non-integer values in datetime

The patch forbids using non-integer values in datetime's `:set()`
for `year`, `month`, `day`, `hour`, `min`, `sec`, `usec`, `msec`,
`nsec` and `tzoffset` keys. `timestamp` can be double, and integer
values allowed in timestamp if `nsec`, `usec`, or `msecs`
provided. An error will be raised when a value of incorrect type
is passed.

Fixes #10391

Title: Update types of datetime values passed to SQL's `CAST();`

`CAST` can accept only integer values for `year`, `month`, `day`,
`hour`, `min`, `sec`, `usec`, `msec`, `nsec` and `tzoffset`.
`timestamp` can be integer or double.
