Avoid using concrete ProviderFactory

[klkvr]

Describe the feature

We're currently using concrete ProviderFactory to obtain DB providers in node components. This results in any generics of database provider implementations leaking into all types requiring DB access. Additionaly this affects compie times as we're becoming bottlenecked on reth-provider crate.

We can slightly change DatabaseProviderFactory trait and use it instead of ProviderFactory:

reth/crates/storage/provider/src/traits/database_provider.rs

Lines 6 to 9 in 94e6939

	pub trait DatabaseProviderFactory<DB: Database> {
	/// Create new read-only database provider.
	fn database_provider_ro(&self) -> ProviderResult<DatabaseProviderRO<DB>>;
	}
