LibWeb: Don't drop single <br/> lines

Browse source 
Previously, when having inline contexts consisting of just a `<br/>`
tag, we would not create a line box.

Ensure that there is always a line box when a line is explicitly being
broken and also ensure it won't be trimmed due to being empty.

This will a fix a number of sites that use `<br>` tags for layouts
between block elements (even though the spec says they shouldn't).
