zephyr: provide a definition of K_MUTEX_DEFINE for CrOS EC OS
Create a compatible K_MUTEX_DEFINE() for CrOS EC OS. This allows us
to use K_MUTEX_DEFINE() in shared code without needing special
Zephyr-only guards.
K_MUTEX_DEFINE() will allow us to stop much of our usage of
k_mutex_init(), which can often be forgotten, leaving mutexes
uninitialized.
BUG=b:177677037
BRANCH=none
TEST=follow up CLs do some conversion to K_MUTEX_DEFINE
they compile in both CrOS EC OS and Zephyr OS
