Backports: fix(op-deployer): fix inspect and state types to respect unmarshalling the state.json (#14889)

[yashvardhan-kukreja]

Description

Backports the fix in op-deployer related to parsing and unmarshalling the state.json's startBlock section correctly to eth.BlockRef through an intermediate serializable type.

Source: #14889

Tests

Running tool: /opt/homebrew/bin/go test -timeout 30s -run ^TestBlockRef_Deserialize$ github.com/ethereum-optimism/optimism/op-deployer/pkg/deployer/state

Some manual testing by modifying the rollup.go to

func RollupCLI(cliCtx *cli.Context) error {
	cfg, err := readConfig(cliCtx)
	if err != nil {
		return err
	}

	globalState, err := pipeline.ReadState(cfg.Workdir)
	if err != nil {
		return fmt.Errorf("failed to read intent: %w", err)
	}

	chainIntent, err := globalState.Chain(cfg.ChainID)
	if err != nil {
		return fmt.Errorf("failed to get chain intent: %w", err)
	}

	fmt.Println(chainIntent.StartBlock)
	return nil
}

With state.json
