enhancement(Autocomplete) allow default selected option(s)

[gselderslaghs]

Proposed changes

This enhancement allows default selected for single or multiselect, as requested per #479
I have implemented an additional option selected that allows an array of alphanumeric ids, given the items ids
This implementation maps the selected ids in the selectedValues object array and handles selection of single or multiple items

Example single select:

M.Autocomplete.init(document.querySelector('.autocomplete'), {
    data: [
        {id: 1, text: "Item 1"},
        {id: 2, text: "Item 2"},
        {id: 3, text: "Item 3"}
    ],
    selected: [3]
});

Example multi select:

M.Autocomplete.init(document.querySelector('.autocomplete'), {
    isMultiSelect: true,
    data: [
        {id: 1, text: "Item 1"},
        {id: 2, text: "Item 2"},
        {id: 3, text: "Item 3"}
    ],
    selected: [1, 2]
});

Additionally changed the selectOption method since selecting values was depending on rendered html in multiSelect, if the minLength option is greater then 0, no results are rendered in the html element, as a result, no options where able to mark as selected, I had to remove the conditional check on the list item and updated selected items using the selectedValues property followed by re-rendering the dropdown component
This change also allows calling the selectOption multiple times as items get pushed in the array without overwriting the full selectedValues array
