LibWeb+LibSyntax: Implement nested syntax highlighters And use them to highlight javascript in HTML source. This commit also changes how TextDocumentSpan::data is interpreted, as it used to be an opaque pointer, but everyone stuffed an enum value inside it, which made the values not unique to each highlighter; that field is now a u64 serial id. The syntax highlighters don't need to change their ways of stuffing token types into that field, but a highlighter that calls another nested highlighter needs to register the nested types for use with token pairs.
