Anas Nashif 0f0cb1a5aa tracing: percepio: update to v4.5.1
A bug fix release with many zephyr with the most significant being a
workaround for the RTT issue we had in the previous release, fixing
the locking problem which could
result in garbled data when using high frequency processors.

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-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.
