Drop obsolete resource usage debug methods from OS class

These methods exist since the dawn of (open source) Godot and have hardly
been updated over time, so they barely work and I'm fairly sure nobody is
using them. (See #46505 for details.)

While some of the functionality they aimed to provide might be useful for
optimization work and introspection, this should likely be redesigned from
scratch with a cleaner and more modern interface (e.g. exposed via the
Performance singleton, or ResourceLoader, and a better API overall).
