Re: [PATCH v8 10/12] entry: Add arch_ptrace_report_syscall_entry/exit()

Differ from generic entry, due to historical reasons, ARM64 need to save/restore during syscall entry/exit because ARM64 use a scratch register (ip(r12) on AArch32, x7 on AArch64) to denote syscall entry/exit.

In preparation for moving arm64 over to the generic entry code, add arch_ptrace_report_syscall_entry/exit() as the default ptrace_report_syscall_entry/exit() implementation. This allows arm64 to implement the architecture specific version.

This allows arm64 to implement the architecture specific version.
