misc: Adjust compiler tests and CI tests

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.
