perf annotate: Switch struct annotation_data::percent to array
So we can hold multiple percent values for annotation line.
The first member of this array is current local hits percent value
(PERCENT_HITS_LOCAL index), so no functional change is expected.
Adding annotation_data__percent function to return requested percent
value from struct annotation_data.
