zephyr: improve shimming for unit tests
* Move the Ztest-related definitions out of test_util and into a shim version of that header. * Add definitions for EC unit tests declaring additional tasks so the task shim will pick them up correctly. * Copy the prng functions into the shimmed test_util. BUG=None BRANCH=None TEST=`make clobber ; make buildall -j ; make runhosttests` Then build the unit tests that have been ported to Ztest, e.g. `zmake configure --test -B build/base32 zephyr/test/base32` for `base32`, `crc`, `hooks`, `i2c`,and `tasks` Signed-off-by: Paul Fagerburg <pfagerburg@google.com> Change-Id: Ia2873a4c2028fcb6960e80f683189def2f3a228d Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/2605231 Tested-by: Paul Fagerburg <pfagerburg@chromium.org> Reviewed-by: Paul Fagerburg <pfagerburg@chromium.org> Commit-Queue: Paul Fagerburg <pfagerburg@chromium.org> Auto-Submit: Paul Fagerburg <pfagerburg@chromium.org>
