This moves the macro related re-exports to `__private` to make it more
obvious for downstream users that they are using an internal api.

The `BlockBuilderProvider` was a trait that was defined in
`sc-block-builder`. The trait was implemented for `Client`. This
basically meant that you needed to import `sc-block-builder` any way to
have access to the block builder. So, this trait was not providing any
real value. This pull request is removing the said trait. Instead of the
trait it introduces a builder for creating a `BlockBuilder`. The builder
currently has the quite fabulous name `BlockBuilderBuilder` (I'm open to
any better name 😅). The rest of the pull request is about
replacing the old trait with the new builder.
# Downstream code changes
If you used `new_block` or `new_block_at` before you now need to switch
it over to the new `BlockBuilderBuilder` pattern:
```rust
// `new` requires a type that implements `CallApiAt`.
let mut block_builder = BlockBuilderBuilder::new(client)
// Then you need to specify the hash of the parent block the block will be build on top of
.on_parent_block(at)
// The block builder also needs the block number of the parent block.
// Here it is fetched from the given `client` using the `HeaderBackend`
// However, there also exists `with_parent_block_number` for directly passing the number
.fetch_parent_block_number(client)
.unwrap()
// Enable proof recording if required. This call is optional.
.enable_proof_recording()
// Pass the digests. This call is optional.
.with_inherent_digests(digests)
.build()
.expect("Creates new block builder");
```

This PR lays the foundation for implementing the archive RPC methods.
The methods implemented by this PR:
- archive_unstable_body: Fetch the block's body (a vector of hex-encoded
scale-encoded extrinsics) from a given block hash
- archive_unstable_genesisHash: Fetch the genesis hash
- archive_unstable_header: Fetch the header from a given block hash
Added unit tests for the methods.
This PR is implementing the methods without exposing them to the RPC
layer; which are to be exposed by a follow-up PR.
