Krzysztof Chruściński b5a7a1909a shell: rtt: Add detection of host presence
If host is not reading RTT data (because there is no PC connection
or RTT reading application is not running on the host), thread will
stuck continuously trying to write to RTT. All threads with equal or
lower priority are blocked then. Adding detection of that case and
if host is not reading data for configurable period then data is
dropped until host accepts new data.

Similar solution is using in RTT logging backend.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
