[3.12] gh-100814: Fix exception for invalid callable value of Tkinter image option (GH-107692) (#107722)

gh-100814: Fix exception for invalid callable value of Tkinter image option (GH-107692)

Passing a callable object as an option value to a Tkinter image now raises
the expected TclError instead of an AttributeError.
(cherry picked from commit 50e3cc9748eb2103eb7ed6cc5a74d177df3cfb13)
