Subject: [Keymap] Update Helix:five_rows OLED code (#14427)
* Stop using snprintf() in keymaps/five_rows/oled_display.c.
The binary size becomes 1350 bytes smaller.
make HELIX=verbose,core-oled helix/rev2/sc:five_rows
(104 bytes over) -> (95%, 1256 bytes free)
make helix/rev3_5rows:five_rows
(528 bytes over) -> (97%, 830 bytes free)
* add matrix scan rate display to OLED for keymaps/five_rows
* add matrix_output_unselect_delay.c to helix keymaps/five_rows
* add GPLv2 header
* apply review comment
