This adds a job level timeout for the compiler tests, allows them to run weekly instead of daily, adds a workflow dispatch option, and changes the 'latests-compilers-all-gem5-builds' jobs to run only the .opt variant. It also adds a ready for review option to the CI tests to run when someone converts a draft pull request.
