Flush delete queue after process frame timers

[KoBeWi]

Same as #85674

Oof, sad that I missed this one until now despite having approved its predecessor and suggested it for early 4.4... #85674 (review)

Now we're again at the stage where such change might be too risky just before beta...
Unless some core folks can confirm this seems safe enough, CC @RandomShaper @hpvb.

Approving to merge and get this tested, but "when" is still TBD.

Sorry?

The mentioned unicode code point turns out to be the toilet emoji! Very appropriate for a PR related to deleting and flushing, but still... I don't know where those characters are supposed to be.

Look at the line just above the warning (KoBeWi wants to merge one commit into godotengine:master from...)

[RandomShaper]

Looks safe to me. Also, it matches what it's documented for Node.queue_free().

The only source of issues I can think of is potential friction with users relying on the former, inconsistent behavior.

Thanks!
