ci: aggregate checks with guardian

[Borda]

What does this PR do?

since almost all these cases are required, we can aggregate them into one check
even we use required jobs, it is quite tricky to have all cases listed and dont miss one
so this will make it easier if we need all and if just a subset we can specify it
