49b01aad74 kernel: Introducing Tracepoint Hook Type Support 
Tracepoint is a predefined hook point in the kernel, compared to Kprobe,
it is more stable and has lower performance overhead, although compatibility
is relatively poor, it is still worth trying

By the way, we have also included the config definitions related to hook types
in Kconfig, to enhance cleanliness

Improve and merge types that do not require hooks

Introducing the hook type prctl

These patches is based on https://github.com/backslashxx/KernelSU/issues/5

cd952f5e45 kernel/ksu.c:Fix word mistakes when enabling CONFIG_KSU_DEBUG (#724) 
According to the instructions in Kconfig, when the `CONFIG_KSU_DEBUG`
option is turned on, KernelSU will run in `debug mode` instead of the
`debug version` mentioned in kernel/ksu.c.
