[PATCH v32 13/13] target/avr: Add tests

[Michael Rolnik <mrolnik@gmail.com>]

1. Avocado test
    The test is based on
    https://github.com/seharris/qemu-avr-tests/tree/master/free-rtos/Demo
    demo which. If working correctly, prints 'ABCDEFGHIJKLMNOPQRSTUVWX' out.
    it also demostrates that timer and IRQ are working

2. Boot serial test
    Print out 'T' through serial port
