feat: Add memo support for swap (#3229)

* feat: Add memo support for swap

* fix: Error on swap page select receiver bottomsheet when picking receiveing currency that's not a wallet type

* feat: exclude providers that do not support memo when receive currency needs it, also show passed memo in confirmation and trade history sheets

* fix: overflow for destination tag on swap confirmation

* Update lib/view_model/exchange/exchange_view_model.dart [skip ci]

* Update lib/exchange/provider/trocador_exchange_provider.dart [skip ci]
