Fixes #21323 (comment).
We've updated the dev mode genesis block to seed some new precompiles. Unfortunately, in dev mode with persistent database we didn't load the genesis from disk, rather always regenerated it and it just happened to match the one on disk. With the changed seeding, any old persisted dev chain became unloadable because of a genesis mismatch.
This PR fixes it by checking the provided data directory for an already initialized chain, and if so, dev mode uses that and does not try to generate a new genesis spec.
