[core/arm] introduce vtable bouncing (#2943)

Browse source 
Basically this just makes functions that go into zero-page or invalid addresses "bounce" back (with a return err of 0) such that it emulates a subroutine returning appropriatedly... this is mainly inspired by [this particular commit](fbb4f5c015); with the key difference of accounting for the scheduler fucking up some random bs.

I don't like this hack but anyways maybe it fixes something?
