The original exception handling has space to optimize and
and some bugs need to be fixed.
* define NANO_ESF
* add the definition of NANO_ESF which is an irq_stack_frame
* add the corresponding codes in exception entry and handler
* remove _default_esf
* implement the _ARCH_EXCEPT
* use trap exception to raise exception by kernel
* add corresponding trap exception entry
* add _do_kernel_oops to handle the exception raised by
_ARCH_EXCEPT.
* add the thread context switch in exception return
* case: kernel oops may raise thread context switch
* case: some tests will re-implement SysFatalHandler to raise
thread context switch.
* as the exception and isr are handled in kernel isr stack, so
the thread context switch must be in the return of exception/isr
, and the exception handler must return, should not be decorated
with FUNC_NORETURN
* for arc, _is_in_isr should consider the case of exception
