This rewrites the REPL precompile script to no longer rely upon ugly hacks for a cross-process copy and instead supports doing the precompile wholly within in the current process.

On Apple Silicon CI this makes REPL precompilation go from 58s to 25s.
That's a surprisingly large improvement!

Working with #undef is unnecessarily trickier and more limited than
using a token, which allows more flexibility with updates.

Launching a subprocess is buggy and error-prone, as partially evidenced
