Change to new, experimental cargo feature resolver

The [new cargo feature resolver](rust-lang/cargo#7820) won't unify features across build deps, dev deps, and targets. This solves our problem of needing to work around feature unification to avoid Clone implementations on private key material. This commit puts back our true dependency information into the Cargo.tomls. Specifically, it adds dev-dependencies that enable features that aren't enabled on normal dependencies. This will cause the feature unification to happen when using the old resolver, but the build will be correct under the new resolver. In order to maintain correct builds in CI, this commit also changes CI to use the nightly cargo with `-Z features=all` but still preserving the rustc toolchain specified in `rustc-toolchain`. Local developer builds will likely still use the `rustc-toolchain` version of cargo with the old resolver, but this shouldn't cause any problems for development.
