spinlock_debug: Move crash to qcom_cpu_vendor_hooks

Reset spinlock_debug.c to commit 0fad51fcb6 ("Snap for 7316566 from
a5293ea1ab to
android12-5.10-keystone-qcom-release").

Add a hook to crash the kernel on a spinlock bug. To avoid having to
create a new tracepoint-based hook for a debug feature, a kretprobe is
used and vendor_hooks will mimic the initial dump that spin_bug would
do.
