Shared: add function combining lines using LineBreak
The `linesToBlock` function takes a list of lines and combines them by appending
a hard `LineBreak` to each line and concatenating the result, putting the result
it into a `Para`. This is most useful when dealing when converting `LineBlock`
elements.
