ec3po: Update platform/ec/ side of ec3po to use threadproc_shim.py.

This removes direct use of multiprocessing module from the platform/ec/
side of ec3po.  Once the third_party/hdctools/ side has been updated to use
threadproc_shim.py as well, that library can be updated with
threading-oriented implementations.

BRANCH=none
BUG=b:79684405
TEST=With a servo_micro connected to an octopus_ite, functionality
involving the EC console continues to work.  I tested dut-control
ec_uart_pty (including using the UART with minicom), dut_i2c_mux,
enable_ite_dfu, get_ite_chipid commands.
