perf vendor events: Update PMC used in PM_RUN_INST_CMPL event for power10 platform

perf vendor events: Update PMC used in PM_RUN_INST_CMPL event for power10 platform

[ Upstream commit 3f8b6e5b11192dacb721d2d28ea4589917f5e822 ]

The CPI_STALL_RATIO metric group can be used to present the high
level CPI stall breakdown metrics in powerpc, which will show:

- DISPATCH_STALL_CPI ( Dispatch stall cycles per insn )
- ISSUE_STALL_CPI ( Issue stall cycles per insn )
- EXECUTION_STALL_CPI ( Execution stall cycles per insn )
- COMPLETION_STALL_CPI ( Completion stall cycles per insn )

Commit cf26e043c2a9 ("perf vendor events power10: Add JSON
metric events to present CPI stall cycles in powerpc)" which added
the CPI_STALL_RATIO metric group, also modified
the PMC value used in PM_RUN_INST_CMPL event from PMC4 to PMC5,
to avoid multiplexing of events.
But that got revert in recent changes. Fix this issue by changing
back the PMC value used in PM_RUN_INST_CMPL to PMC5.

Result with the fix:

 ./perf stat --metric-no-group -M CPI_STALL_RATIO <workload>

"--metric-no-group" is used for forcing PM_RUN_INST_CMPL to be scheduled
in all group for more accuracy.
