PRs targetting `qcom/debian/latest` are not build-tested in CI

For this, all we need is a premerge yml in qcom/debian/latest (example) that calls to daily yml on pull_request, and daily needs to have workflow_call inputs to be used as reusuable workflow. Daily yml then will automatically parse all matrix variants specifications, and it will delegate to build-kernel-deb, which then delegates to build-kernel-debusine (debian family) AND build-kernel-ubuntu (ubuntu family).

To initiate the whole chain, all is needed is a call to daily on pull_request.
