util: uartupdatetool (UUT): Add tool to flash firmware by UART

When the FLPRG# strap pin is set to active low, and npcx7 chip is reset,
it will enter uut mode. This CL adds the host tool to communicate with
npcx chip in uut mode to flash ec firmware via UART port.

BRANCH=none
BUG=none
TEST=No build errors for make buildall.

------------------------------------------------------------------------
1. Connect the servo connector (J24) on npcx7 EVB to servo board v2 via
flex cable.
2. Manually turn the switch SW1.6 to "ON" on npcx7 EVB.
3. Reset ec by issuing Power-Up or VCC1_RST reset.
4. Manually turn the switch SW1.6 to "OFF" on npcx7 EVB.
5. Move npcx7_evb from array BOARDS_NPCX_7M7X_JTAG to BOARDS_NPCX_UUT in
flash_ec.
6. "./util/flash_ec --board=npcx7_evb."
