core: Refactor NewBlockchain -- Add blockChainConfig

[makinje16]

What

This PR modifies core.NewBlockChain and adds in a new blockChainConfig struct along with supporting types and methods.

Why

Issue #20280 mentions that the number of arguments to core.NewBlockChain had gotten out of hand and a config structure was desired. This issue was raised 5 years ago and the amount of refactoring needed has increased since.

Testing

• Unit Tests Updated

Reference

• Issue Make a core.BlockChainConfig to simplify NewBlockChain #20280
• First attempt to fix this issue refactor NewBlockChain #20301
• Second attempt to fix this issue core: add BlockChainConfig  #22968

	bcConfig := core.NewBlockChainConfig(
		core.WithCacheConfig(cache),
		core.WithGenesis(gspec),
		core.WithVmConfig(&vmcfg),
	)

In the scenario above, you basically define a new config. But, it doesn't make it a lot more ergonomical compared to if you had just made the config public. Then the corresponding code would look like this instead:

	bcConfig := core.BlockChainConfig{
		CacheConfig: cache,
		Genesis: gspec,
		VmConfig: &vmcfg,
	}

I don't really see any benefit of this pr.. ?
