/**
 * Given the state and an array of slot names, will break out `slots` and `slotProps`
 * collections.
 *
 * The root is derived from a mix of `components` props and `as` prop.
 *
 * Slots will render as null if they are rendered as primitives with undefined children.
 *
 * The slotProps will always omit the `as` prop within them, and for slots that are string
 * primitives, the props will be filtered according to the slot type by the type system.
 * For example, if the slot is rendered `as: 'a'`, the props will be filtered for acceptable
 * anchor props. Note that this is only enforced at build time by Typescript -- there is no
 * runtime code filtering props in this function.
 *
 * @deprecated use slot.always or slot.optional combined with assertSlots instead
 *
 * @param state - State including slot definitions
 * @returns An object containing the `slots` map and `slotProps` map.
