perf report: Show inline stack for browser 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 -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 -g address --inline

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