Revert "zephyr: pull in the version string from zmake"

This reverts commit 10809eb023d475681b45863e68d906fae4667eda.

Reason for revert: Causing build errors b/197287679

Original change's description:
> zephyr: pull in the version string from zmake
>
> Zmake computes a version string and stores it in FRID/FWID, but this
> was never plumbed all the way out into the version functionality in
> the OS, which was reporting the version generated by
> util/getversion.sh.
>
> Add a mechanism to generate the version header from zmake and replace
> the getversion.sh generation with that.
>
> BUG=b:184832251
> BRANCH=none
> TEST=provided unit tests
> TEST=get this version string on posix-ec:
> posix-ec_v2.6.73347-cmsis:c3bd20,ec:c814a9,hal_stm32:f8ff8d,os:efe095
