tree: do not pass custom click to item edited

[nathanfranke]

CC @trollodel, see #47665

This was preventing the item_edited signal from being called on Tree (broke editor features).

The custom_item_clicked signal doesn't seem to be used by the editor, so it should be safe to emit both signals for now, while mantaining the mouse parameter where used.

(broke editor features)

Just to be sure, what brokes specifically?

My bad, I mean it broke the Editor->Editor Features dialog. Disabling editor features does not save or update, since the dialog relies on the item_edited signal.

Should be safe for the editor because the signal doesn't seems to be used by the editor and even if it's used, any connection must return if the signal is not triggered by the right mouse button.
