Add defaults for tkinter __init__ methods (#11391)

Add defaults for `tkinter`'s `__init__` methods, see #10947 

Some notes about specific arguments:
- `variable` and `textvariable`: The default value (using `dict`) is consistently `""` but this doesn't match the annotated `Variable` type so I didn't fill these in
- `Message(padx, pady)`: The default value is `-1` which is not allowed according to the documentation so I didn't fill this in
- `Toplevel(use)`: The default value is always `""` but this doesn't match the annotated `int` type so I didn't fill this in
