[ComboBox] Autocomplete implementation

[thyhmdo]

Ref link for implementation #13903

Example: https://github.com/microsoft/fluentui/blob/master/packages/react/src/components/ComboBox/ComboBox.tsx
Repo for ComboBox https://github.com/microsoft/fluentui/blob/master/packages/react/src/components/ComboBox/ComboBox.tsx

This looks like it's not an easy update and going to take some time

Blocked by #13749

Might be blocked by needing to refactor ComboBox off of <Downshift/> and over to useCombobox.

After more discussion, the dev team feels that this is blocked by the refactor:

• Refactor ComboBox to use useComboBox instead of <Downshift> component #14684

[tay1orjones]

In addition to the existing behavior spec for this, we should consider the APG example for this that includes some nice functionality that uses the selection range

Very similar to what Taylor referred here:

• Click on the input
• Start writing out the first letter
• All options match the typed letter(s) will be filtered out
• It highlights and spells out all the options
• The first option (following the typed letters)
