Update the Starlark changelog

Summary: There are 650 commits, and I don't think anyone has time to produce a great changelog. Kinda sucks, but better a release than not, so hey ho.

bump allocative version for hashbrown 0.12.3 -> 0.14.3

Summary:
Already released new allocative version to crates.io, also updating internally. We can keep the starlark-rust 0.12.3 version since I updated allocative before updating starlark in crates.io locally.

I had to bump the version for allocative as well to get the hashbrown fix into the release.

Will make a new github release for starlark-rust when I land this.

Store module private variables in module, not in locals

Summary:
When loaded symbols are no longer reexported (D30534539), module private symbols (e. g. loaded symbols) are stored in local stack.

This diff changes privates to store them in module itself (like with public module variables).

The reasons for this diff:
* eventually replace `ValueRef` with explicit cell objects
* to implement loaded constants propagation

This diff it useful as is because it improves error message on trying to import private symbols. For example, for this code:

```
# a.bzl
x = 1

# b.bzl
load("a.bzl", "x")

# c.bzl
load("b.bzl", "x")
```

Previously error message was `Variable 'x' not found`, now error message is `Module symbol 'x' is not exported`.
