Athira Rajeev befee3775b perf powerpc: Update global/local variants for p_stage_cyc
Update the arch_support_sort_key() function in powerpc to enable
presenting local and global variants of sort key 'p_stage_cyc'.

Update the "se_header" strings for these in arch_perf_header_entry()
along with instruction latency.
