Transparent windows on wayland must be pre-multiplied after transfer-function encoding

## Bevy version

0.17

## What you did

Run the transparent_window example.

## What went wrong

There is fringing where the bevy logo is translucent.

## Additional information

Wayland assumes that pre-multiplication is performed after transfer-function encoding. There is no way to achieve this in Vulkan with built-in functionality, therefore I think the simplest solution to achieve this is as follows:

1. Keep everything else as is.
2. Immediately before presentation, run the following compute shader on the swapchain image:
1. Apply the sRGB EOTF
2. Unpremultiply
3. Apply the sRGB OETF
4. Premultiply
