x86/dumpstack: Add get_stack_info() interface
valid_stack_ptr() is buggy: it assumes that all stacks are of size
THREAD_SIZE, which is not true for exception stacks. So the
walk_stack() callbacks will need to know the location of the beginning
of the stack as well as the end.
Another issue is that in general the various features of a stack (type,
size, next stack pointer, description string) are scattered around in
various places throughout the stack dump code.
Encapsulate all that information in a single place with a new stack_info
struct and a get_stack_info() interface.
