eth, cmd: remove syncTarget from eth config (#26330)
--syncTarget is a feature for development purpose in post-merge world. Previously
it's added into eth.Config. But it turns out that's a stupid idea.

- syncTarget is a block object, which is hard to be put in config file(large)
- syncTarget is just a dev feature, doesn't make too much sense to add it in config file

So I remove it from the eth config object. And it also fixes the #26328
