fix: Remove circular dependencies across workspace (#3023)
Circular dependencies are problematic in several ways:

- They result in cognitive overhead for developers, in trying to figure out what depends on what.
- They present `cargo` with limits in what order the crates can be compiled in.
- They invalidate build caches unnecessarily thus forcing `cargo` to rebuild certain crates.
- They cause problems with tooling such as `release-please`.

To actually break the circular dependencies, this patch inlines the uses of `development_transport` in the examples and tests for all sub-crates. This is only meant to be a short-term fix until https://github.com/libp2p/rust-libp2p/issues/3111 and https://github.com/libp2p/rust-libp2p/pull/2888 are fixed.

To ensure we don't accidentally reintroduce this dependency, we add a basic CI that queries `cargo metadata` using `jq`.

Resolves https://github.com/libp2p/rust-libp2p/issues/3053.
Fixes https://github.com/libp2p/rust-libp2p/issues/3223.
