perf list: Display metric expressions for --details option

Browse Source 
Display metric expression itself when --details is specified.

Current list with no details:

  # perf list metrics
  ...
  TopDownL1:
    IPC
         [Instructions Per Cycle (per logical thread)]
    SLOTS
         [Total issue-pipeline slots]
  ...

Detailed output with metric formula:

  # perf list --details metrics
  ...
  TopDownL1:
    IPC
         [Instructions Per Cycle (per logical thread)]
         [inst_retired.any / cpu_clk_unhalted.thread]
    SLOTS
         [Total issue-pipeline slots]
         [4*(( cpu_clk_unhalted.thread_any / 2 ) if #smt_on else cycles)]
  ...
