[PATCH 0/3] Add a generated list of hooks in hook-list.h

This goes on top of my just-submitted trivial Makefile fixes[1], and adds a list of hooks in hook-list.h, similar to the existing config-list.h.

We can then error when a C API provides us with an unknown hook, so non-type-checked things in the codebase like find_hook("proc-receive") now effectively have a type check of sorts (well, we'd catch a typo in our tests).

These changes are currently at the end of the ab/config-based-hooks-base series[2], I'm carving them out to make that topic even easier to digest. We can this without any of the "git hook run" stuff.

We also had a big but inaccurate list of hooks in builtin/help.c, as part of submitting a bugreport. That's now using githooks(5) as a source of truth.

This also builds on Windows with cmake, unlike the outstanding [2] `restart of "config-based-hooks"` series, at least that part of the CI now passes, and the change to contrib/buildsystems/CMakeLists.txt looks trivially correct to me.
