Similar to the wgpu access, the `unstable-winit-030` feature exposes a
`slint::winit_030` module, which in turn re-exports `winit` but also
provides access to the `WinitWindowAccessor` trait. The
`BackendSelector` is extended to provide a way to hook into window
attribute creation as well as providing a custom event loop builder,
similar to what `i_slint_backend_winit::BackendBuilder` provides.
- Create a `slint::wgpu_24` module
- Re-export `wgpu` in it
- Place the WGPU config types used by the `BackendSelector::require_wgpu_24` function in it, and remove the 24 infix.
As an upside, this also adds the feature guard to the docs at least for the `wgpu_24` module.
The `require_wgpu_24` function accepts either a fully setup WGPU, or one
can configure individual aspects such as features/limits.
The wgpu_texture example uses this to add push constants to the required
features and thus eliminates the need for uniform buffers.
This adds a `unstable-wgpu-24` feature that exposes WGPU types in the
GraphicsAPI enum, adds `require_wgpu_24()` to the backend selector,
and adds a conversion from `wgpu::Texture` to `slint::Image`.
The `require_wgpu_24()` function in the selector will be extended in the
future (before the next release) to permit specifying additional aspects
of the WGPU configuration.

Based on API review, PlatformBuilder becomes BackendSelector with
a slightly smaller API surface but more options, such as selecting
Metal or Vulkan rendering.
