perf report: Show inline stack for stdio mode

perf report: Show inline stack for stdio mode

If the address belongs to an inlined function, the source information
back to the first non-inlined function will be printed.

For example:

1. Show inlined function name
   perf report --stdio -g function --inline

     0.69%     0.00%  inline   ld-2.23.so           [.] dl_main
            |
            ---dl_main
               |
                --0.56%--_dl_relocate_object
                          _dl_relocate_object (inline)
                          elf_dynamic_do_Rela (inline)

2. Show the file/line information
   perf report --stdio -g address --inline

     0.69%     0.00%  inline   ld-2.23.so           [.] _dl_start_user
            |
            ---_dl_start_user .:0
               _dl_start rtld.c:307
               /build/glibc-GKVZIf/glibc-2.23/elf/rtld.c:413 (inline)
               _dl_sysdep_start dl-sysdep.c:250
               |
                --0.56%--dl_main rtld.c:2076
