These are now covered by switches inside each case.
This helps typos but it's unneccessarily clever.
This removes some runtime validation for the hydration path because we generally don't do this kind of validation against the props there. Only if the path ends up mismatching in the children somehow. This leads to some duplication but I plan on unifying later.
We actually only use this for BOOLEANs anyway.

I confirmed that the attribute-behavior fixture yields the same result as main (with the last fix included). |

This is in line with the refactor I already did on Fizz earlier and brings Fiber up to a similar structure. We end up with a lot of extra checks due the extra abstractions we use to check the various properties. This uses a flatter and more inline model which makes it easier to see what each property does. The tradeoff is that a change might need changes in more places. The general structure is that there's a switch for tag first, then a switch for each attribute special case, then a switch for the value. So it's easy to follow where each scenario will end up and there shouldn't be any unnecessary code executed along the way. My goal is to eventually get rid of the meta-programming in DOMProperty and CSSProperty but I'm leaving that in for now - in line with Fizz. My next step is moving around things a bit in the diff/commit phases. This is the first step to more refactors for perf and size, but also because I'm adding more special cases so I need to have a flatter structure that I can reason about for those special cases. DiffTrain build for [520f7f3](520f7f3)
