fix(workflows): Drop GEN & Add support for debian, buildroot

fix(workflows): Stop building GEN device family

- GitHub pages are introduced for customers/ developers
to get access the latest bleeding-edge documentation

- DEVFAMILY=GEN is not used in production by any OS & hence
contains irrelevant information [1]. So, stop building it
as a part of CICD.

@cshilwant , Would it make sense to completely eliminate the 'General' variable? There are many files which have this variable so it would make sense to remove them in one swoop because otherwise context might be lost?

@AashvijShenai Eliminating GEN config might need more internal discussion.
I ack in removing the GEN config but there are many references of "General_family" in the entire documentation which needs cleanup.

This PR was intended to avoid it from building in GitHub pages CICD as it contains information that's irrelevant for customers/ developers.

Well, hold on. @praneethbajjuri I've been meaning to ask you about the GEN and CORESDK DEVFAMILY configs, as they never made any sense on their own and I had never seen a deployment of them. Are these being used anymore? Are we safe to prune them?

We should also prune any ifconfig directives using parameters listed under these configs.

[praneethbajjuri]

Ok to prune gen.
I use coresdk platform for validating some common foundation components docs and configs which are published at coresdk level.so, don't prune coresdk platform

[StaticRocket]

Alright. We'll merge the CI cleanup now and have a followup to drop the config and modify the source.
