Add stack overflow detection to SW emulator

[clundin25]

#1722 uncovered a latent stack overflow. We need to add tests / checks / ci to make sure we are not hitting any stack overflows.

rust-embedded/cortex-m-rt#34 this explains a zero cost abstraction to achieve it

That looks like a good approach (cross-linking the tracking bug #1665).

Adding stack monitoring in the simulator has a few advantages:

• Doesn't touch any of the prod artifacts.
• Allows for data collection, so we can monitor for code paths that are close to overflowing.

I think it makes sense to implement both.

That makes sense.
Also I think hitless update might be impossible to achieve when changing the stack location. Although I think it's a good idea to do that in 2.0 where the rom is not yet finalized.
