Chips: Removed in V18

[PierreB40]

As I said in this issue: https://github.com/primefaces/primeng/issues/16091 The deletion of the Chips component in V18 seems to me to be a mistake. Autocomplete and chips don't have the same parameters, and the same uses. The proposed alternative is not flexible enough: if chips disappears, autcomplete must be able to cover 100% of the possibilities offered by Chips.
