SQL: Implement null safe equality operator `<=>` (#35873)
This operator handles nulls in different way than the normal `=`.
If one of the operants is `null` and the other not it returns `false`.
If both operants are `null` it returns `true`. Therefore in contrary to
`=`, which returns `null` if at least one of the operants is `null`, this one
never returns `null` as a result.

Closes: #35871

SQL: Implement IN(value1, value2, ...) expression. (#34581)
Implement the functionality to translate the
`field IN (value1, value2,...)` expressions to proper Lucene queries
or painless script or local processors depending on the use case.

The `IN` expression can be used in SELECT, WHERE and HAVING clauses.

Closes: #32955
