Simon Hausmann 3101104f5c Switch from WGPU 24 to WGPU 25 
- Use a version of FemtoVG that uses WGPU 25
- Rename the unstable-wgpu-24 feature and wgpu_24 module
- Fetch bevy from a revision on master branch that switches to WGPU 25
- Move the bevy example out of the common workspace: That way users of the repo don't get bevy pulled from git, unless they want to build the bevy example.

WGPU Texture Import Example

This example application demonstrates how import a WGPU texture into a Slint scene:

  1. First a graphical effect is rendered using WGPU, into a texture.
  2. The texture is imported into a slint::Image and set on an Image element.
  3. A scene of Slint elements is rendered with the texture shown in the Image.

This is implemented using the set_rendering_notifier function on the slint::Window type. It takes a callback as a parameter and that is invoked during different phases of the rendering. In this example the invocation during the setup phase is used to prepare the pipeline for WGPU rendering later. Then the BeforeRendering phase is used to render the graphical effect with WGPU into a texture. Then the texture is imported and Slint will render the scene of elements with the texture.

Since the graphical effect is continuous, the code in the callback requests a redraw of the contents by calling slint::Window::request_redraw().
