sched_ext: Sync tools autogen enum headers from the scx repo

Sync the four autogen enum headers with the scx repo at c9b90b3ad3d0
("scheds/include: Sync with kernel sched_ext/for-7.4 (c6fe97c34a1a)"). The
enum definition and ABI tables pick up the enumerators the kernel gained
since the last sync. The two lookup tables are taken verbatim from scx's
copies so the files stay identical: their task state lookups move from the
removed scx_task_state to scx_ent_flags, where 7203d77d6e04 ("sched_ext:
Simplify task state handling") put the states, and until now resolved to
zero. The only entry the kernel copy gains is SCX_RQ_BAL_KEEP, which scx
keeps for older kernels and which zero-fills here.
