Ensure updates are applied when diffInCommitPhase is on (#26977)
When we diffInCommitPhase there's no updatePayload, which caused no update to be applied. This is unfortunate because it would've been a lot easier to see this oversight if we didn't have to support both flags. I also carified that updateHostComponent is unnecessary in the new flag. We reuse updateHostComponent for HostSingleton and HostHoistables since it has a somewhat complex path but that means you have to remember when editing updateHostComponent that it's not just used for that tag. Luckily with the new flag, this is actually unnecessary since we just need to mark it for update if any props have changed and then we diff it later.
