Add VT Server

[ad3154]

This is a draft for cleaning up and eventually pulling in the VT server files.

• Created a base class for VT client & server so they can share common enums
• Added the concept of a "managed working set" which stores client specific data for a VT server
  • This also provides the object pool deserializer. Deserialization is handled in a worker thread to avoid tying up a server while it's parsing an object pool.
• Added VT Server (somewhat WIP, needs lots of Aux-N stuff for example)
  • The actual server interface is abstract, though I provide an implementation for some app specific things like get_supported_small_fonts_bitfield... probably need to re-evaluate some abstraction before merging.
• Fixed a number of warnings in various places, which I got when building with JUCE

Now that I can work on the VT properly, I think it makes sense to squash all this and merge it in, and then make incremental reviews as we iterate on the VT.

You okay with that @GwnDaan ?
