tools/sched_ext/include: Add __COMPAT_HAS_scx_bpf_select_cpu_and macro 



scx_bpf_select_cpu_and() is now an inline wrapper so
bpf_ksym_exists(scx_bpf_select_cpu_and) no longer works. Add
__COMPAT_HAS_scx_bpf_select_cpu_and macro that checks for either the
struct args type (new) or the compat ksym (old) to test availability.
