workqueue: Derive the standard attrs from the workqueue flags

alloc_and_link_pwqs() picks one of three static attrs arrays indexed by
WQ_HIGHPRI, and branches to a separate apply_workqueue_attrs_locked()
call for percpu, ordered and unbound workqueues. The arrays differ only
in the nice level and the ordered bit, which the flags already say.

Build the attrs from the flags instead. alloc_wq_std_attrs() sets nice
for WQ_HIGHPRI and ordered for __WQ_ORDERED, which collapses the three
branches into one call and drops the three arrays along with their
workqueue_init_early() loop.

The ordering WARN now sits behind its own __WQ_ORDERED test rather than
the unbound branch. __WQ_ORDERED is internal and every macro that sets it
pairs it with WQ_UNBOUND, so the WARN covers the same workqueues as
before.

The attrs are allocated per creation now. apply_wqattrs_prepare() already
allocates one on the same path, including in workqueue_init_early(), so
that is not a new constraint, and it only copies what it is given, so the
caller can free them once apply_workqueue_attrs_locked() returns.
