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.
