Say "component" for the component

"Embedded" already means something here: the embedded package is the
widget build. Where a comment meant Element Call running as a React
component inside a host application, it now says so, and the params it
starts from are `componentProperties`. "Host" stays the word for the
application on the other side, whether that is a widget container or an
application rendering the component.
