arch: Add proptest as a dev-dependency

Not all invariants can be effectively enforced by Rust's type system
and when this is the case we typically want tests that assert that the
promised invariants do indeed hold.

To get good confidence that our invariants do indeed hold we want to
check against many inputs, but having to write down many inputs is
tedious, and we may also be "biased" in our choices.

Property based testing helps here as it provides several randomly
generated inputs for us and we can focus on just writing the
test logic.

We thus add the popular user friendly `proptest` library as a
dev-dependency in order to write property based tests in follow up
commits. We emphasize that this will be particularly important in
a follow up PR where we have some relatively complex logic for
filtering MSRs.
