Replace `#pragma once` by traditional include guards for consistency

`#pragma once` was used in a few files, yet we settled on using
traditional include guards instead.

The PooledList template comment was also moved to allow editors
such as Visual Studio Code to display the comment when hovering
PooledList.

`app.h` was renamed to `app_uwp.h` to be less generic for the
include guard.
