LibWeb: Adjust create_document_for_inline_content() for future use

Browse source 
(Apologies for bad commit title, it's hard to explain in such a short
space!)

We're going to need to call this for producing markdown and gemini
documents, both of which need a Document and Realm to fetch the entire
response body, so that they can then generate their HTML. So this
commit modifies `create_document_for_inline_content()` to take a lambda
instead of a fixed HTML string, to support these uses.

Also, we always return a nonnull pointer, so make that the return type.

This is a move and change in the same commit, (Sorry!) but all the
changes are to the function signature and step 6.
