OHOS environment setup for different kernels
Given that OHOS will run on multiple different kernels we need
a straight-forward way of setting up build environment.
There are many possible solutions, so we need to pick a sensible one
that'll suit our needs.

Configuration / adaptation layers for kernels withing meta-openharmony
One option is to make configuration / adaptaion layer per kernel which
will contain all necessary bitbake configs (e.g. local.conf.sample,
bblayers.conf.sample, etc.) that can be used together with oe-init-build-env
script:

TEMPLATECONF=meta-openharmony/meta-ohos-zephyr/conf . oe-init-build-env


This will create a build/conf directory based on the contents of meta-ohos-zephyr/conf
where all required layers and configs can be defined. The same applise for other
kernels, like FreeRTOS, Liteos or any other Linux-based distro.
Below is a sequence diagram of how this could look like for Zephyr:
