Write out builtins with TypeScript + Minify them (#2999)
* start work drafting how builtins will work
* work on ts builtin
* builtins stuff so far
* builtins
* done for today
* continue work
* working on it
* bindings so far
* well, it builds. doesnt run
* IT RUNS
* still lots of ts errors but it is functional
* sloppy mode
