perf annotate browser: Display titles in left frame

The annotate browser is divided into 2 frames. Left frame contains 3
columns (some platforms only have one column).

For example:

                   │26  int compute_flag()
                   │27  {
 22.80  1.20       │      sub    $0x8,%rsp
                   │25          int i;
                   │
                   │27          i = rand() % 2;
 22.78  1.20     1 │    → callq  rand@plt

While it's hard for user to understand what the data is.

This patch adds the titles "Percent", "IPC" and "Cycle" on columns.

Percent  IPC Cycle │
                   │25  __attribute__((noinline))
                   │26  int compute_flag()
                   │27  {
 22.80  1.20       │      sub    $0x8,%rsp
                   │25          int i;
                   │
                   │27          i = rand() % 2;
 22.78  1.20     1 │    → callq  rand@plt

The titles are displayed at row 0 of annotate browser if row 0 doesn't
have values of percent, ipc and cycle.
