LibWeb: Add 'PseudoElement' as a CSS SimpleSelector::Type

Browse source 
Same reasoning again! This is the last one.

While I was at it, I added the two remaining CSS2.2 pseudo-elements,
::first-line and ::first-letter. All 4 are handled in the new CSS
parser, including with the compatibility single-colon syntax. I have
not added support to the old parser.
