[tkinter.ttk] Added type annotations for Style, fix some other incomplete parts

[MarcellPerger1]

• Added type annotations for methods in tkinter.ttk.Style
• 2 other functions improved (setup_master, Panedwindow.forget)

[MarcellPerger1]

Is this a stubtest bug? It says

error: tkinter.ttk.Style.element_create is inconsistent, stub argument "elementname" has a default value but runtime argument does not
Stub: in file /home/runner/work/typeshed/typeshed/stdlib/tkinter/ttk.pyi:137

But on line 137, it has no default argument...
https://github.com/MarcellPerger1/typeshed/blob/c86e49931e093d6b9aadcc75d8588908a2c30274/stdlib/tkinter/ttk.pyi#L137-L158

It also seems to concatenate the overloaded functions' signatures together as it infers the signatue in the stub to be:

Inferred signature: def (self: tkinter.ttk.Style, elementname: builtins.str = ..., elementname: builtins.str = ..., etype: Literal['image'] = ..., etype: Literal['from'] = ..., _default_image: Union[tkinter._Image, builtins.str] = ..., themename: builtins.str = ..., fromelement: builtins.str = ..., *imagespec, border: Union[builtins.str, builtins.float, tuple[Union[builtins.str, builtins.float]], tuple[Union[builtins.str, builtins.float], Union[builtins.str, builtins.float]], tuple[Union[builtins.str, builtins.float], Union[builtins.str, builtins.float], Union[builtins.str, builtins.float]], tuple[Union[builtins.str, builtins.float], Union[builtins.str, builtins.float], Union[builtins.str, builtins.float], Union[builtins.str, builtins.float]]] = ..., height: Union[builtins.str, builtins.float] = ..., padding: Union[builtins.str, builtins.float, tuple[Union[builtins.str, builtins.float]], tuple[Union[builtins.str, builtins.float], Union[builtins.str, builtins.float]], tuple[Union[builtins.str, builtins.float], Union[builtins.str, builtins.float], Union[builtins.str, builtins.float]], tuple[Union[builtins.str, builtins.float], Union[builtins.str, builtins.float], Union[builtins.str, builtins.float], Union[builtins.str, builtins.float]]] = ..., sticky: builtins.str = ..., width: Union[builtins.str, builtins.float] = ...)

elementname appears twice after each other, there's two separate etype arguments... I have no clue what's going on here, but IMHO it doesn't look like the intended behavior

[MarcellPerger1]

For the pre-commit.ci failure, I have no clue why flake8 isn't recognizing the usage of _ElementCreateArgs on line 110

stdlib/tkinter/ttk.pyi:97:5: Y047 Type alias "_ElementCreateArgs" is not used

[TeamSpen210]

Kinda awkward but you could do *imagespec: *tuple[tkinter._ImageSpec, *tuple[_ImageStatespec, ...]]. Not sure if this would be problematic to use though for code completion though.

I think you should just ignore the stubtest error.

Sorry about taking so long to get to this. First I was going to go through this in full detail, but eventually I realized I don't know anywhere near enough about ttk to do that.

I'm planning to trust you that this is correct enough, and just merge once CI is green.
