Michael Sproul 258b28469e Update consensus code and tests to v0.12.3 (#1655)
## Proposed Changes

Update test vectors for v0.12.3, and introduced configurable `proportional_slashing_multiplier`.

Also makes `YamlConfig` a bit safer by making every field access in `apply_to_chain_spec` explicit, and removing the `#[serde(default)]` attribute, which would instantiate missing fields to type defaults! Risky!
