Implement proper decorationless popups by specifying the type of the child window with with_type()
With this commit, different kind of child windows can be created
- Popups: Special windows without any decoration which can be positioned relative to the parent
- Window: Normal window with a parent or not
The type can be specified during creation of the Window using the window_attributes and the with_type() function. As default a normal Window is used. If Popup is choosen a parent must be specified, otherwise the Popup creation fails with an Error returned by the new() function.

The `text` field on `KeyEvent` was hardcoded to `None` on Android,
making it impossible for custom `NativeActivity` subclasses that
show the IME to receive functional text input using *for example* the
existing `winit-egui` crate which relies on this field being set.
Use `Key::to_text()` on press events to derive `text` from
`logical_key`, matching the convention used by the Windows and macOS
backends.
Supposedly that doesn't include all kinds of special virtual unicode
keys, but at least the basics work this way.
Allow updating IME state atomically to make it easier for platforms
where it's atomic by its nature, like Wayland. The old API is marked
as deprecated and is routed to the new atomic API.
