[PATCH 0/2] MR5708: user32/tests: Rename and expand use of winevent_hook_todo flag.

[Esme Povirk (＠madewokherd)]

After an earlier rewrite, this flag works with all message types. So this expands its usage to some cases where we were using the `optional` flag for messages that are missing on Wine.

Some of the comments saying Wine is broken for not sending them turned out to be wrong - they're not always sent on Windows either - and in those cases the comments were removed.
