Added aria roles to eui-select and eui-poplist
Added aria-owns attribute to eui-select
Added menu tole to poplist.listView, menuitem to poplist.listItem, added TextSupport attribute bindings for various aria-components (necessary for combobox attrs on {{input}})
Added support for focus on highlighed in poplist listview
Focus highlighted poplist option

Once an option is highlighted, we need to call 
.focus() on it's representation in the DOM. Doing 
it this way guarantees that the item will be read 
by screen readers.
