* Update the nix build configuration.

Remove the old shell.nix with some legacy versions pinned and replace it with a flake-based shell. It installs rust via rustup instead of fenix to be more generally compatible with the guidelines.

This also adds the rust-toolchain.toml spec with all the components required for wasm, and everything else to make rust-analyzer & clippy happy.

* Also add the top level flake for hacking on the substrate as whole

* Remove the envrc and ignore it instead.

* Remove the top-level configuration

* Prepare `sc-network` for `ProtocolController`/`NotificationService`

The upcoming notification protocol refactoring requires that protocols
are able to communicate with `sc-network` over unique and direct links.
This means that `sc-network` side of the link has to be created before
`sc-network` is initialized and that it is allowed to consume the object
as the receiver half of the link may not implement `Clone`.

Remove request-response and notification protocols from `NetworkConfiguration`
and create a new object that contains the configurations of these protocols
and which is consumable by `sc-network`. This is needed needed because, e.g.,
the receiver half of `NotificationService` is not clonable so `sc-network`
must consume it when it's initializing the protocols in `Notifications`.

Similar principe applies to `PeerStore`/`ProtocolController`: as per current
design, protocols are created before the network so `Protocol` cannot be
the one creating the `PeerStore` object. `FullNetworkConfiguration` will be
used to store the objects that `sc-network` will use to communicate with
protocols and it will also allow protocols to allocate handles so they
can directly communicate with `sc-network`.

This pull request brings support for compiling the runtime with stable Rust. This requires at least
rust 1.68.0 to work on stable. The code is written in a way that it is backwards compatible and
should automatically work when someone compiles with 1.68.0+ stable.
