## Description

Add an abstraction (trait and macro) over system packages. Now there are
a number of methods that need to be added for each one, to get:

- Framework ID
- module BCS bytes
- CompiledModule
- MovePackage
- Object

To avoid us forgetting one, and to simplify adding new ones in future.

## Test Plan

```
$ cargo simtest
$ env SUI_SKIP_SIMTESTS=1 cargo nextest run
```
