primitives: Add additional re-exports

We have a few types that can reasonably be re-exported at the root of
both `primitives` and `bitcoin`.

- `ScriptHash` and `WScriptHash` - we export all the other hash types
- `BlockVersion` alias to `block::Version`
- `TxVersion` alias to `transaction::Version`
