perf report: Introduce --inline option

It takes some time to look for inline stack for callgraph addresses.  So
it provides new option "--inline" to let user decide if enable this
feature.

  --inline:

  If a callgraph address belongs to an inlined function, the inline stack
  will be printed. Each entry is the inline function name or file/line.
