g: re-implement usb console with usb-stream configuration.
This patch introduces CONFIG_USB_CONSOLE_STREAM, which implements
usb-console with usb-stream configuration, intending to remove
code redundancy between the previous implementation (usb_console.c)
and usb_stream.c.
Flash usage decreases by 224 bytes, and RAM usage by 40 bytes.
BUG=b:138447451
BRANCH=cr50
TEST=Checked cr50 USB console and cr50 UART console respectively.
Key-in response and output are working well:
./util/uart_stress_tester.py /dev/ttyUSB0 -t 300 --debug
