[Core] Unite half-duplex and full-duplex serial drivers (#13081)

Browse source 
* Unite half-duplex and full-duplex serial driver.

* Add full duplex operation mode to the interrupt based driver
* Delete DMA UART based full duplex driver
* The new driver targets #11930

* Fix freezes with failing transactions in half-duplex

* Increase default serial TX/RX buffer size to 128 bytes

* Correctly use bool instead of size_t
