sched/coredump: introduce enum task_dumpable
Replace the SUID_DUMP_DISABLE/USER/ROOT preprocessor constants with
enum task_dumpable. Numeric values are preserved (kernel.suid_dumpable
sysctl and prctl(PR_SET_DUMPABLE) ABI), so this is a pure rename with
no behavioral change.
Subsequent commits relocate dumpability onto a per-task structure
where the enum type will allow stronger type-checking on the new API.
