uart_buffering: add tx_buffer_full() API
To aid in system level UART console performance testing a test
function needs to know when the UART console buffer is full. This
patch provides an API for that.
BRANCH=none
BUG=b:38448364
TEST=verified proper operation of the chargen CLI command which uses
this API.
