kprobes: Add generic kretprobe trampoline handler
Add a generic kretprobe trampoline handler for unifying the all cloned /arch/* kretprobe trampoline handlers. The generic kretprobe trampoline handler is based on the x86 implementation, because it is the latest implementation. It has frame pointer checking, kprobe_busy_begin/end and return address fixup for user handlers.
