Propagate DevCancellation to BioPrompt

This CL aims to propagate the developer cancellation signal to the
biometric prompt, by creating a 'wait/notify' system based on the
underlying viewModel's mutableState. This specifically modifies
BiometricState to contain a new property that acts as the 'notifier' for
cancellation in the SysService.
