Andrew Boie cdb94d6425 kernel: add k_panic() and k_oops() APIs
Unlike assertions, these APIs are active at all times. The kernel will
treat these errors in the same way as fatal CPU exceptions. Ultimately,
the policy of what to do with these errors is implemented in
_SysFatalErrorHandler.

If the archtecture supports it, a real CPU exception can be triggered
which will provide a complete register dump and PC value when the
problem occurs. This will provide more helpful information than a fake
exception stack frame (_default_esf) passed to the arch-specific exception
handling code.
