Implemented Some-typed literals in SQL

[egormanga]

Description of Changes

Ability to, given a table:

#[table(name=table)]
struct Table {
	option: Option<i32>,
}

do:

INSERT INTO table (option) VALUES (0);

instead of getting:

Error: The literal expression `0` cannot be parsed as type `(some: I32 | none: ())`

• Companion pull request for #3606.

API and ABI breaking changes
