Supports hard and soft interrupts. In the current implementation, soft interrupt callbacks will only be called when the VM is executing, ie they will not be called during a blocking kernel call like k_msleep. And the behaviour of hard interrupt callbacks will depend on the underlying device, as well as the amount of ISR stack space. Soft and hard interrupts tested on frdm_k64f and nucleo_f767zi boards.
