[Breaking] Scoping generic extension methods

This was causing every object to have additional methods appearing in the IDE and on the documentation, which can be very confusing for new developers and irritating for experienced ones.

This means that these extension methods no longer work with IntPtr and "IReferencable" types, but this feature was unused.

Seperate extension methods for "IReferencable" types could be created without "Dispose" in the name and instead use the "Release" naming.
