bpf: Add KF_SPINLOCK_SAFE flag for kfuncs under bpf_spin_lock
Introduce the KF_SPINLOCK_SAFE kfunc metadata flag in BTF so kfuncs may
be explicitly marked as safe to call while holding bpf_spin_lock.
Allow kfuncs defined in kernel modules to be marked with KF_SPINLOCK_SAFE.
Example: BTF_ID_FLAGS(func, $kfunc_name, KF_SPINLOCK_SAFE)
