LoongArch: Replace kretprobe with rethook
This is an adaptation of commit f3a112c0c40d ("x86,rethook,kprobes:
Replace kretprobe with rethook on x86") and commit b57c2f124098 ("riscv:
add riscv rethook implementation") to LoongArch. Mainly refer to commit
b57c2f124098 ("riscv: add riscv rethook implementation").
Replaces the kretprobe code with rethook on LoongArch. With this patch,
kretprobe on LoongArch uses the rethook instead of kretprobe specific
trampoline code.
