Title: core 109.23.00-rc1

# 109.23.00

## core

- Exposed `Core.Std.Flags` module.
- Made the `Heap` module implement `Container.S1`.
- Added module `Ref.Permissioned`, which is a ref with `read_only` /
`read_write` access control.
- Exposed the unique id in `Type_equal.Id`.

This allows, e.g. hash tables indexed by unique ids.
- Removed the use of `Obj.magic` from the implementation of
`Type_equal.Id.same`.

It is not needed because the `Id.t` contains a `Uid.t` and we can
just use `Uid.equal`.
