LibWeb: Use available space to resolve table container width

Browse source 
Using avilable space directly while resolving table container width
allows to avoid assigning it to table wrapper box content width which
sometimes involves infinite (saturated) values.

Also this allows to get rid of set_max_content_width() which is a hack
that allows to bypass set_content_width() to assign infinite
(saturated) width to a box.

Closes https://github.com/SerenityOS/serenity/issues/19521
