Add a new hosted test environment "processor".
This is meant as a build target used when the
code is not built for a real target
but as part of a test in a hosted environment
(for ex. as a test environment like Zephyr's
native_sim target).
When building for this target PROJECT_PROCESSOR
should be set as "hosted".
In this, the "metal_sleep_usec()" call
is expected to be provided by the system folder
headers.
