LibWeb: Insert newlines for line breaks in preformatted white-space

Browse source 
When inserting a line break in a contenteditable with preformatted
white-space (pre, pre-line, pre-wrap), insert a newline character (\n)
instead of a <br> element. Use <br> only for padding at end of line to
ensure the cursor can be placed on the new line.
