Drop Caml runtimes and primitives (#6984)

* remove Caml io/formatting/converting stuffs

* remove Lexing/Parsing/Parser completely

* remove Caml_sys completely

* remove hash/digest/Hashtbl

* format jscomp/test again

* restore Hashtbl.hash

* update lib artifacts

* remove stale tests

* remove Caml compile time constants

* remove (almost) Caml String/Bytes/Char/Stream

* remove floatarray

* remove Caml int32/int64/nativeint

* remove uint32 liternal which has never exposed

* migrate caml_{type}_compare/min/max primitives

* Drop OCaml `Array` module

* drop other OCaml DS modules

* fix hashtbl size hint

* rename promise primitive

* remove unused code

* update artifacts

* remove unused module

* Drop `%lazy_force` primitive

* remove unused code

* remove/replace all remain `caml_*` primitives

* Remove unwanted float primitives

* remote unused/unnecessary exn primitives

* migrate dict primitive

* rename #import to %import

* migrate obj and option primitives

* migrate hash primitives

* remove unused code path

* remove unused internal primitives

* migrate already ones from internal primitives

* specialize every primitives in a path

* drop/rename more interfaces

* merge exn primitive modules

* move curry primitive module

* move util primitives

* update artifacts

* fix gentype test

* add empty modules for core OCamlCompat

* rename ref primitives

* bring back a few primitives for Core compatibility

* bring back error reporting on unknown #prim

* add more compat

* Js_runtime_modules -> Primitive_modules

* Remove unused code path

* Remove unused code path (floatarray) in frontend

* remove unused builtin types

* fix binding

* refactor primitive externs

* bring back Array module accessing pattern

* more compat, deprecation, and migrate stdlib-406 dir completely

* cleanup ninja dependencies

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

* add deprecation on pervasives

* tmp: try fix

* clean a bit

* added %modfloat primitive, added Pervasives.mod_float compat

* added Pervasive string conversion compat

* do not mention Js module

* add clean-rewatch recipe

-  This has type: list<int>
-  But this function argument is expecting: list<float>
-
-  The incompatible parts:
-    int vs float
+  This has type: int
+  But it's being used with the +. operator, which works on: float
+
+  Floats and ints have their own mathematical operators. This means you cannot add a float and an int without converting between the two.
+
+  Possible solutions:
+  - Ensure all values in this calculation has the type float. You can convert between floats and ints via Belt.Float.toInt and Belt.Int.fromFloat.
+  - Change the operator to +, which works on int
 
   You can convert int to float with Belt.Int.toFloat.
   If this is a literal, try a number with a trailing dot (e.g. 20.).
