kernel: consolidate error handling code

* z_NanoFatalErrorHandler() is now moved to common kernel code
  and renamed z_fatal_error(). Arches dump arch-specific info
  before calling.
* z_SysFatalErrorHandler() is now moved to common kernel code
  and renamed k_sys_fatal_error_handler(). It is now much simpler;
  the default policy is simply to lock interrupts and halt the system.
  If an implementation of this function returns, then the currently
  running thread is aborted.
* New arch-specific APIs introduced:
  - z_arch_system_halt() simply powers off or halts the system.
* We now have a standard set of fatal exception reason codes,
  namespaced under K_ERR_*
* CONFIG_SIMPLE_FATAL_ERROR_HANDLER deleted
* LOG_PANIC() calls moved to k_sys_fatal_error_handler()
