Refactor our CI yamls

Description

As we're using CI for some time, I found that it actually brings unnecessary complications to have a layer of yamls just designating what is done on pr, optionally on pr, and on push. This can be directly added to each of the jobs.

Another effect is that in the "Actions" tab, we won't have On PR, Optional On PR, and On Push where each includes several different jobs. We will now have Build device, build and run tests, and pre-commit , which will run both on PR branches and main.

List of the changes

• Created a build-and-run-all-tests.yml which wraps build-tests and run-tests for all archs. This just nicely corresponds exactly to previous on-pr-opt.
• Deleted on-pr, on-pr-opt and on-push ymls
• Added to all referenced .ymls the config to run on pr and/or on push, so that same jobs are called on same triggers.
• Added timeout parameter to a couple of jobs.
• I will change in settings which jobs are mandatory, if they are now named slightly different.
