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.
