/**
 * Functionally, this type helper is equivalent to the identity type — i.e. `type Identity<T> = T`.
 * However, wrapping generic object mappings in this type significantly reduces the number
 * of instantiation expressions processed, which increases TypeScript performance and
 * prevents "Type instantiation is excessively deep and possibly infinite" errors.
 *
 * This works because TypeScript doesn't create a new level of nesting when encountering conditional generic types.
 * @see https://github.com/microsoft/TypeScript/issues/34933
 * @see https://github.com/kysely-org/kysely/pull/483
