g: add rx_handled into USB_STREAM_CONFIG
The variable rx_handled tracks how many of the bytes in the HW FIFO
was moved into the incoming queue. It used to be defined as local
static variable for multiple USB_STREAM_CONFIGs, and could cause a
problem if multiple USB downstream traffic get heavier. It should
be defined for each USB_STREAM_CONFIG.
This patch add rx_handled into USB_STREAM_CONFIG, which tracks
how many of the bytes in the HW FIFO was moved into the incoming
queue.
BUG=None
BRANCH=None
TEST=manually ran uart_stress_tester.sh and flash_ec on Bob.
