feat: make reth-stages independent of concrete DatabaseProvider

[klkvr]

alike #10921

• Extracts unwind methods into DbTxMut extension trait DbTxUnwindExt
• Changes Stage generic from DB to Provider
• Moves take_state and remove_state methods to StateChangeWriter, unsure what's best place for those, lmk if they should be somewhere else

Next step could be to make Pipeline generic over provider factory, removing its dependency on NodeTypesWithDB. However, this would make scope of the PR bigger without much benefit, so can be done in a follow up

this is pretty cool, this removes the hardcoded db type and instead relies on trait bounds for the various stages impl.

this will be more flexible

very nice.
