Fix blending for CameraOutputMode::Skip (#16157)
# Objective

Currently, if we have two cameras with the same output texture, one with
`CameraOutputMode::Write` and one with `CameraOutputMode::Skip`, it is
possible for the `CameraOutputMode::Write` camera to be assigned alpha
blending (which is the fallback blending when multiple cameras write to
the same output texture), although it is the only camera writing to the
output texture. This may or may not happen every restart of the app,
because the camera iteration order in prepare_view_upscaling_pipelines
isn't consistent. Since this is random behaviour I consider this a bug
and didn't add a migration guide.

## Solution

In `prepare_view_upscaling_pipelines` make sure we don't consider
cameras with CameraOutputMode::Skip to be outputting something to the
output texture.

## Testing

I ran a few examples to make sure nothing obvious is broken. There is no
example using CameraOutputMode::Skip, so I only tested the change in my
own App where this was relevant, which however isn't public.
