Add NativeProcessProtocol unit tests

Summary:
NativeProcessProtocol is an abstract class, but it still contains a
significant amount of code. Some of that code is tested via tests of
specific derived classes, but these tests don't run everywhere, as they
are OS and arch-specific. They are also relatively high-level, which
means some functionalities (particularly the failure cases) are
hard/impossible to test.

In this approach, I replace the abstract methods with mocks, which
allows me to inject failures into the lowest levels of breakpoint
setting code and test the class behavior in this situation.
