LoongArch/ftrace: Add HAVE_DYNAMIC_FTRACE_WITH_ARGS support
Allow for arguments to be passed in to ftrace_regs by default. If this
is set, then arguments and stack can be found from the pt_regs.
1. HAVE_DYNAMIC_FTRACE_WITH_ARGS don't need special hook for graph
tracer entry point, but instead we can use graph_ops::func function to
install the return_hooker.
2. Livepatch requires this option in the future.
