arm64/cfi,bpf: Support kCFI + BPF on arm64
Currently, bpf_dispatcher_*_func() is marked with `__nocfi` therefore
calling BPF programs from this interface doesn't cause CFI warnings.
When BPF programs are called directly from C: from BPF helpers or
struct_ops, CFI warnings are generated.
Implement proper CFI prologues for the BPF programs and callbacks and
drop __nocfi for arm64. Fix the trampoline generation code to emit kCFI
prologue when a struct_ops trampoline is being prepared.
