LibWeb: Check for HTML integration points in the tree constructor

Browse source 
This particularly implements these two points:
- "If the adjusted current node is an HTML integration point and the
   token is a start tag"
- "If the adjusted current node is an HTML integration point and the
   token is a character token"

This also adds spec comments to the tree constructor.
