perf sort: Sort disabled and full predicated flags

Browse Source 
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 full predicated.

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