switch libagx to the precompilation pipeline. see the big comment in the previous commit for why we're doing this. while doing so, we move some dispatch stuff. there was so much churn from precompile that this avoids doing the churn twice. that new header will be used for DGC down the road. there's also a small vtn/bindgen patch in here to skip bindgen'ing entrypoints, as that conflicts with the new dispatch macros. this is the sane behaviour, we just need to do the full precomp switch across the tree at once.
