Add support for stacktrace in dummy thread which is used to run
the early system initialization code before the kernel switches
to the main thread.
On RISC-V, the dummy thread will be running temporarily on the
interrupt stack, but currently we do not initialize the stack
info for the dummy thread, hence check the address against the
interrupt stack.
