Currently the toggle total period view on the annotate TUI
shows the number of samples, not period like below.

  $ perf annotate --show-total-period

Percent│
       │
       │
       │    Disassembly of section .text:
       │
       │    0000000000109a90 <_mcount@@GLIBC_2.2.5>:
       │      sub    $0x38,%rsp
     3 │      mov    %rax,(%rsp)
     3 │      mov    %rcx,0x8(%rsp)

This output has two problem:

  1) Wrong column i.e. 'Percent'
  2) Show number of samples, not period

So fix the toggle total period view on the annotate TUI like below.

Event count│
           │
           │
           │    Disassembly of section .text:
           │
           │    0000000000109a90 <_mcount@@GLIBC_2.2.5>:
           │      sub    $0x38,%rsp
   2204022 │      mov    %rax,(%rsp)
   2207405 │      mov    %rcx,0x8(%rsp)

So now this becomes a sym_hist_entry? (nr, period)
