framework/src/iotbus: add new APIs in iotbus to test new UART TCs

- add new APIs in iotbus to test UART TCs, APIs are: iotbus_uart_rxavailable() iotbus_uart_txready() iotbus_uart_txempty() - add new TCs to test UART rxavailable, txready and txempty APIs. Signed-off-by: Deepak Sharma <[email protected]>
