tools/sched_ext: Receive updates from SCX repo
Receive tools/sched_ext updates form https://github.com/sched-ext/scx to
sync userspace bits:
- basic BPF arena allocator abstractions,
- additional process flags definitions,
- fixed is_migration_disabled() helper,
- separate out user_exit_info BPF and user space code.
This also fixes the following warning when building the selftests:
tools/sched_ext/include/scx/common.bpf.h:550:9: warning: 'likely' macro redefined [-Wmacro-redefined]
550 | #define likely(x) __builtin_expect(!!(x), 1)
