changed the title
Now the only `runtime` dir is the built-in primitive literally Removed dependency hacks from `ninja.js` and make the dependency graph clearly `others` -> `runtime` Removed `Belt_internals` module, use compiler primitive instead Removed `runtime/js`, so made `others/js` only source of JS bindings Primitives shouldn't rely on JS any binding

Resolves #5779
Rationale
This removes runtime modules and primitives that exist for OCaml compatibility.
The original BuckleScript tried distinguishing between OCaml-inherited primitives and custom primitives (
?prim) and js primitives (#prim), but it didn't stick well.Since we gave up OCaml compatibility, it added unnecessary complexity with indirection, making it hard to predict where specialization would be performed.
So here I unify all primitives into a single prefix grammar of
%. There is still#primitive, but it exists temporarily for compatibility or is meant to be internal to the compiler and not exposed to the frontend.Changes
This PR contains many breaking changes
Primitive_object.updateDummy(formallyCaml_obj.update_dummy) behavior is now the same as theObject.assignand doesn't specially handleArrayinstances. See discussion from Improve obj dup using spread syntax #7043. But this is safer because it is only used inmodule recbindings.String.get: (string, int) => charbehavior is now the same as theString.prototype.codePointAt. It was potentially buggy with existing char primitives, but this fixes it.

All primitives except # prefixed should eventually be treated as "features" and documented. We can rename all by a new convention for primitive names, but the old names should be kept for a while for compatibility.
Primitives are declared in two different places because they are processed separately before and after
Lam_convert. It is difficult to change and to determine the types used or not used, resulting in many dangerous assertions.Ultimately, I want to consolidate the primitive declarations into one place and make them easier to manage.
