[kernel] Unittests of kernel stack depth handling Add a unittest that checks that we can receive interrupts and handle mp_sync_exec calls when thread context has used up half of the kernel stack. The first test is simple and probablistic - it allocates a large on-stack buffer and waits a bit for any (potential) interrupts. If an interrupt were to take > 1/2 the kernel stack to handle, we would see an architecture-specific stack overrun failure. The second test is deterministic and ensures we can run an mp_sync_exec handler (that signals an event) while half the kernel stack is used from thread context by a buffer.

Pink + Purple == Fuchsia (a new operating system)
Fuchsia is a modular, capability-based operating system. Fuchsia runs on modern 64-bit Intel and ARM processors.
Fuchsia is an open source project with a code of conduct that we expect everyone who interacts with the project to respect.
