Modified serial_adapter so log are allowed when using USB
CDC ACM serial port emulation.
Added dedicated thread for log processing of the highest application
priority. This allows to transmit all logs without adding k_sleep
anywhere else int the code.
Introduced boot log thread is simpler than the default log threat
which decreases flash footprint by a few dozen bytes.
Added configuration for nrf52840_pca10056 which shows how
to enable looging along with USB - among other, thread log
processing is required.

Zephyr will soon no longer add the drivers subdirectory of the include
hierarchy to the search path, so references to driver headers must
include the drivers/ prefix.

zephyr changes the way in which it provide name of
serial device used by serial recover.
see: https://github.com/zephyrproject-rtos/zephyr/pull/18752
This path introduce build time configuration of device name
which is set to exact the same device which was set before.

The old log subsystem has been deprecated in Zephyr.
Migrate to the new subsystem to avoid compilation warnings.
In-place log processing is selected as it is required as MCUBoot is
one thread application.

fixup
The UART device ISR in serial_adapter expected the device
to fire an interrupt for each byte that was received.
Although this might have worked for some devices it wouldn't
work for USB. This commit fixed the issue by modifying the ISR
according to the uart.h documentation.

Due to an issue described here:

interrupts are not enabled when multithreading is disabled.
Enable interrupts to allow the serial recovery mode UART to receive
characters.

Serial adapter uses the zephyr UART driver in interrupt mode for
providing communication capabilities needed for the boot serial
recovery mode.
This module provide API similar to mynewt console module.
Serial adapter module can not be compiled along with
the zephyr uart console module so this case is checked.
