Missing function to bind switch state (lv_switch_bind_checked)

[xamix]

LVGL version

v9.0.0

What happened?

I can find the lv_button_bind_checked for buttons but not the equivalent for switch (lv_switch_bind_checked)
Is this function missing or do I need to use another function?
I tryed lv_button_bind_checked on a switch and it seem to work...

Regards

How to reproduce?

Actually lv_button_bind_checked should work for buttons, switches and checkboxes too. It just binds the LV_STATE_CHECKED state of the widget. I think we should rather call this function lv_obj_bind_checked. What do you think?

Switch and checkbox are checkable by default. lv_obj_add_flag(btn, LV_OBJ_FLAG_CHECKABLE) is needed before lv_button_bind_checked on a button. Meanwhile lv_button_bind_checked works "out of the box" on checkboxes. Since there's nothing about the implementation of lv_button_bind_checked that relies on anything button-specific, and works "out of the box" on those widgets other than button, yes I think it's a good idea to rename it to lv_obj_bind_checked.

Might be good to mention the LV_OBJ_FLAG_CHECKABLE flag in the docstring of lv_obj_bind_checked.

@liamHowatt It seems all good. Could you send a PR?
