Add ability to disable callbacks temporarily #20802
Description
It may be useful to update some attributes on an object that has callbacks temporarily and we don't want those callback signals being processed during that time.
I guess we could add a disabling_callbacks() context manager on CallbackRegistry?

In Qt, this is
Widget->blockSignals, and in GTK, it isg_signal_handlers_block_*. Wx has awxEventBlockerthat you add on a widget to temporarily stop events. Not sure if Tk has anything similar.IOW, it seems like 'block' is the common term for this for events, though I don't know if these callbacks qualify as 'events'.
