ShirkNeko 68f2f5a0ae 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 backslashxx/KernelSU#5
