Leaving out all independent formulas (see #62201) is it doable to migrate all the rest in one huge PR?

So, what did we learn from the first round? It ran for 53 hours, and built 35 bottles. But, most of that time is spent in a couple of formulas: rust takes 3 hours to build, and 6 more hours to test all its dependents; node is a couple of hours; llvm also. Also, it tried many times to rebuild libxml2 from source, and kept failing.

Failures

libxml2 fails to build, upstream has a patch (https://gitlab.gnome.org/GNOME/libxml2/-/issues/149):
