Karl Zhang fec5ed6077 trusted-firmware-m: Add initial plumbing for TFM
This commits adds a config option to build a PSA trusted-firmware-m
(TF-M) application image for the secure processing environment, and
configures the Zephyr application image for the non-secure processing
environment. The secure and non-secure environment images will be
linked together via the veneer function table that is produced as an
artifact of the TF-M build process.

Andy Ross 7defd09b97 samples: Add MetaIRQ dispatch sample
MetaIRQs are described in docs and exercised in tests, but there's no
sample explaining how they are intended to be used to perform
interrupt bottom half processing.

This simple tool spawns a set of worker threads at different
priorities (some cooperative) which process "messages" (which require
CPU time to handle) received from a fake "device" implemented with
timer interrupts.  The device hands off the events directly to a
MetaIRQ thread which is expected to parse and dispatch them to the
worker threads.

The test demonstrates that no matter the state of the system, the
MetaIRQ thread always runs synchronously when woken by the ISR and is
able to preempt all worker threads to do its job.

Alexey Brodkin 7c3498dc43 Samples: Add SMP Pi
This sample showcases efficient utilization of SMP system
with processing of independent resource-hungry workloads.

With no cross-dependencies between workers and no usage of shared
resources (during heavy-lifting itself) we may demonstrate almost
linear scaling of efficiency. I.e. 2 cores do the same amount of
calculations twice faster than only 1 core. 4 cores complete
the same calculations 2 times faster than 2 cores.

David B. Kinder 505cc2bb0e doc: use :zephyr_file: where appropriate
A new role :zephyr_file: is available that renders to a link to the file
or folder in GitHub.  Find appropriate references using :file: and
convert to :zephyr_file: to take advantage of its linking capability.
