stacktrace: header: repair kernel-doc comments

- use the "typedef" keyword when describing a typedef
- add a Returns: section

to prevent these kernel-doc warnings:

Warning: include/linux/stacktrace.h:20 function parameter
 'stack_trace_consume_fn' not described in 'bool'
Warning: include/linux/stacktrace.h:20 expecting prototype for
 stack_trace_consume_fn(). Prototype was for bool() instead
Warning: include/linux/stacktrace.h:58 No description found for
 return value of 'arch_stack_walk_reliable'
