LibWeb: Replace most of our default UA stylesheet with spec rules

The HTML spec provides a set of suitable default CSS rules for our UA
stylesheet, so let's use those instead of inventing our own. :^)

Note that I had to replace "foo-block-start" properties with "foo-top"
since we don't support the block/inline direction based properties yet.
