Simplify the stacktrace code:
- remove the unused task argument to save_stack_trace, it's always
current
- remove the all_contexts flag, it's alwasy 0

CONFIG_KALLSYMS=n case is obviously wrong, though it is harmless since
CONFIG_KALLSYMS is always enabled with CONFIG_STACKTRACE for now.

If the PC was ret_from_irq or ret_from_exception, there will be no
more normal stackframe. Instead of stopping the unwinding, use PC and
RA saved by an exception handler to continue unwinding into the
interrupted context. This also simplifies the CONFIG_STACKTRACE code.

Fix build error due to stacktrace API change. Now save_stack_trace()
tries to save all kernel context, including interrupts and exception.
Also some asm code are changed a bit so that we can detect the end of
current context easily.

Implement stacktrace interface by using unwind_stack() and enable lockdep
support in Kconfig.
