Move towards C23, improve events and vcall macros

Another big one. Here's a list of things:

- Since the upcoming C23 standardises typeof(), use it as an extension
  for the time being in order to allow passing arbitrary types as
  macro/codegen parameters. It wouldn't have been a big leap to do this
  even without standardisation since it's apparently an easy extension
  to implement - and also, to be honest, this project is essentially glued
  to Clang anyway so who cares.

- Likewise, bool, true and false are becoming pre-defined, so
  pre-pre-define them now in order to get the benefit of not having to
  remember one header everywhere.

- Really ungodly/amazing vcall macro stuff now allows us to call C++
  virtual functions like regular C functions. It's pretty cool!

- Events can now take arbitrary parameters and come in two types:
  regular events and predicates.

All this makes the base code even uglier but makes the feature
implementation nicer. In other words, it places more of the cognitive
burden on myself and less on other people who might want to contribute.
This is a good tradeoff, because I'm a genius.
