fix(combobox): cache management for option values and labels

[jzempel]

Description

Lack of memoized variable coordination presented a corner-case bug for consumers where value-label affinity could be lost. For example:

a multiselect combobox is rendered with possible options of [{ label: A, value: Apple }], then updated with [{ label: A, value: Apple }, { label: B, value: Basil }]. With a selectionValue of [ Apple, Basil ], these should map to show the labels "A" and "B". However, on first load it shows "A" (label) and "Basil" (value) instead as it’s stuck with the initial options despite the updated ones

Detail

The updated code moves previously memoized option labels, selectedValues, disabledValues, and hiddenValues into an object cache along with values. By removing the coordination, these values can be collectively reinitialized (and memoized) every time the combobox options change.
