Fix the doc warning attribute and document remaining items for bevy_window (#9933)

# Objective

Complete the documentation for `bevy_window`.

## Solution

The `warn(missing_doc)` attribute was only applying to the `cursor`
module as it was declared as an inner attribute. I switched it to an
outer attribute and documented the remaining items.
