AK: Add JsonValue::{is,as}_integer() methods

Browse source 
The existing `is_i32()` and friends only check if `i32` is their
internal type, but a value such as `0` could be literally any integer
type internally. `is_integer<T>()` instead determines whether the
contained value is an integer and can fit inside T.
