[mediaplayer] Add nullability to (generated and manual) bindings

[tj-devel709]

This PR aims to bring nullability changes to MediaPlayer.
Following the steps here:

1. I am looking for any !missing-null-allowed! in this frameworks ignore files and applying them
2. Changing any == null or != null to is null and is not null

❤️ the test.

I wonder if the test will randomly fail on CI in the future, since the strangest things sometimes do, and something in MediaPlayer feels like it could, but let's add it and remove if it acts up.
