feat: virtualize search over all filters list (#298)

[hunterckx]

Notes:

• I've made it so the Autocomplete doesn't handle the list items, and instead has its ListboxComponent parameter set to a component that renders the list without using the children passed to it by the Autocomplete. My reasoning is that we aren't using the Autocomplete as an actual autocomplete anyway, and it's more straightforward to give the virtualized list full control over the items.
• I created a copy of the existing VariableSizeList component (putting it under SearchAllFilters/components without any name changes), and used that for the virtualized list, which means I ended up deleting the AutocompleteListbox component (after moving its sizing function into VariableSizeList).
• I've kept just the single map for storing element heights, so I have it give each option a unique key constructed from the category key and value key; see applyMenuFilter in the new VariableSizeList.tsx (particularly line 211). Hopefully this is a reasonably simple strategy -- I feel that it might be simpler than other solutions such as using a separate map for each category.
• Referencing MUI's virtualization example, I've used contexts to provide information to components that are passed to the Autocomplete and the virtual list (specifically for the ListboxComponent and the OuterElementType respectively)
