Subject: Revert "dix: Use DeliverGrabbedEvent for implicit passive grabs
 (#25400)"

Reported-by: Florian Mickerl <florian@mickler.org>
"this regresses my desktop. fluxbox is not able to move the windows around
anymore. also popup of context-menue does not work. (well sometimes it does,
but then the fluxbox-keyboard-shortcuts do not work)"

This reverts commit 351d11fd466fae731df860a6ff4cf50ad565f43f.
