[Keymap] clean up helix:five_rows keymap (#10866)

* Makes the OLED driver used by the helix:five_rows keymap switchable.

* use TOP/drivers/oled/oled_driver.c
  `make HELIX=stdole helix:five_rows`
* use helix/local_drivers/ssd1306.c
  `make HELIX=oled helix:five_rows`

* Separated the OLED related code from keymap.c and moved it to oled_display.c.

* scan rate without OLED
  * make HELIX=verbose,dispoff,scan helix/rev2:five_rows
    use Helix original code

* clean up helix/rev2/keymaps/five_rows/keymap.c

* update five_rows/oled_display.c

* update helix/rev2/keymaps/five_rows/keymap.c: remove LAYOUT_kc()

* Ported the keymap from helix/rev2:five_rows to helix/rev3_5rows:five_rows.

* update five_rows/oled_display.c

* add License comment
