Add egui::Window::title_frame (#8353)

Browse Source 
* [X] I have followed the instructions in the PR template


Add a way to set the frame for the content and for the title of the
window
- `self.frame` will be used for the margins of the body
- `self.title_frame` will be used for the margins of the header (title)
