fix(multi-select): resolve a11y violations (#1072)

Browse source 
- role="listbox" children require the role="option" attribute
- add a "aria-multiselectable" attribute to the listbox menu
- move "aria-label" attribute from listbox to listbox menu
- listbox field should not have a "combobox" role when expanded (the non-filterable variant serves as a button)
