Wrapping support in HorizontalLayout and VerticalLayout

[rolfsmeds]

Describe your motivation

Wrapping is the easiest way to create responsive layouts, but our two primary layout components lack an API for enabling wrapping.

Describe the solution you'd like

API for wrapping in HorizontalLayout and VerticalLayout, e.g.

Flow: layout.setWrap(true);

WC: <vaadin-horizontal-layout theme="wrap">

The API simply applies flex-wrap: wrap; on the layout root.

(flex-wrap: wrap-reverse can be kept outside the scope for now, and I feel that it's too niche to warrant an enum-based API. Instead, an optional second parameter could be used in Flow, e.g. setWrap(boolean wrap, boolean reverse) if there is demand for it.)
