[PATCH 23/25] perf sort: Sort disabled and full predicated flags

[Leo Yan]

According to the Arm ARM (ARM DDI 0487, L.a), section D18.2.6
"Events packet", apart from the empty predicate and partial
predicates, an SVE or SME operation can be predicate-disabled
or fully predicated.

To provide reliable results, introduce two predicate types for
these cases.
