LibSyntax+LibGUI+LibJS: Move JS syntax highlighter to LibJS

Browse source 
This is a little bit messy but the basic idea is:

Syntax::Highlighter now has a Syntax::HighlighterClient to talk to the
outside world. It mostly communicates in LibGUI primitives that are
available in headers, so inlineable.

GUI::TextEditor inherits from Syntax::HighlighterClient.

This let us to move GUI::JSSyntaxHighlighter to JS::SyntaxHighlighter
and remove LibGUI's dependency on LibJS.
