Replace walk_stackframe() with generic arch_stack_walk() which already wraps walk_stackframe() and is the generic mechanism used in archs like arm64 to build the kernel callchain.
Also decouples perf from the internal walk_stackframe unwinder which is modified in later commits to accept a different function signature, which warranted this change.
