[FEATURE] Autcomplete component

[astagi]

Describe the solution you'd like

Create an Autocomplete component based on the original Bootstrap Italia Autocomplete component:
https://italia.github.io/bootstrap-italia/docs/form/autocompletamento/

⚠️ In order to have a great support for a11y, Autocomplete base component is based on Accessible Autocomplete which supports React natively (https://github.com/alphagov/accessible-autocomplete#using-with-react). Accessible Autocomplete dependency is already included in Bootstrap Italia and doesn't need to be added on the main package of this project.

• Create the base component if it doesn't exist or make it compatible with the BI 2 version
• Cover all the variants
• Create a Storybook series based on the documentation or update it for BI 2

Notes:

• use BI classes to style the component.
• minimize the amount of extra CSS to style in this component
