Rename RichText source to rawText and move it into members

Replace the RichText.source extension property (a when over every subtype)
with a rawText member declared on RichText and implemented directly by each
inheritor: RichTextPlain.rawText = text, the wrapping entities delegate to
text.rawText, and custom emoji / mathematical expression / anchor fall back
to their own representation. Update the RichBlockPreformatted and media
markdown builders and the formatting tests accordingly.
