When doing a self-review I noticed it was me who added it. I am sure it was not added when implementing the saving logic for Android, seems like it was a remnant of the debugging stage. Saving still works without it.

This pull request fixes a subset of #5492 by saving the application state when the
suspendedevent is received on Android. This way, even if the user exits the app and closes it manually right after changing some state, it will be saved sincesuspendedgets fired when the app is exited. It does not fix theon_exitfunction not being fired - this seems to be a winit bug (theexitingfunction in the winit application handler trait is not called on exit). Once it gets fixed, it may be possible to remove logic introduced by this PR (however, I am not sure how it would handle the app being killed by the system when in the background, that would have to be tested).I've tested the logic by:
In all of these instances, the state was saved (the last one being a pleasant surprise). It was tested on the repository mentioned in #5492 with my forked repository as the source for eframe (I unfortunately am not able to test it in a larger project of mine due to dependence on "3rd party" egui libraries (like egui_notify) which do not compile along with the master branch of eframe (different versions of egui), but I believe it should work in the same manner in all scenarios). Tests were conducted on a Galaxy Tab S8 running Android 14, One UI 6.1.1.
CI passed on my fork.
