Add Atmel Studio projects for ATMega4809 and AVR128DA48 (#159)

Browse source 
* Added explicit cast to allow roll over and avoid integer promotion during cycles counters comparison in recmutex.c.

* Fixed type mismatch between declaration and definition of function xAreSemaphoreTasksStillRunning( void ).

* Added Atmel Studio demo projects for ATMega4809 and AVR128DA48.

* Per https://www.freertos.org/upgrading-to-FreeRTOS-V8.html, I'm updating portBASE_TYPE to BaseType_t.

Signed-off-by: Yuhui Zheng <10982575+yuhui-zheng@users.noreply.github.com>

* Update register test for ATmega4809
- to cover r28, r29, r31.
- call public API taskYIELD() instead of portYIELD().

* Update ATmega4809 readme.md to include info for serial port setup, and minor wording fix.
