1. Use buildjet for the longer Linux CI workflows.
2. Continue with `ubuntu-latest` for shorter Linux CI workflows.
3. Use a large GitHub-hosted Windows runner.

4. Make CIFuzz run on merge to main or release branch, not
in the pull request
Two runs each of the original workflow files and the updated
workflows in this PR. One run of the GitHub Large Ubuntu runners
is included; these are clearly between the regular GitHub and BuildJet
runners in performance.

A few very short workflows are being left on GitHub-hosted runners, like
licenses and gofmt. These benefit from the quicker dispatch to GitHub
hosted runners.
--------
For Windows and the windows.yml test run:
- the regular `windows-latest` runner takes about 6 minutes 20 seconds
- there is enough variability run to run that we get the same ~4 minute
run with:
- a GitHub-hosted large runner
- a self-hosted Windows Server 2022 in an AWS t3.xlarge
- a self-hosted Windows Server 2022 in an AWS c6i.xlarge
Since there is not a gain from operating our own runner, we'll pay
GitHub to operate a Windows large runner.
