CLN: Clean NDFrame.__finalize__ signature
`NDFrame.__finalize__` doesn't do anything with `method` or `kwargs` so removing them from the signature and all calls. Had to change a few tests which overrode this method with another that also included those arguments.
I think @TomAugspurger had some plans for this? https://github.com/pandas-dev/pandas/pull/28394 is still a WIP, though I split out the finalize bits.

But we'll want `method` for us, and subclasses may be using the other arguments. Sounds like this may not make sense so I'll go ahead and close
