Decrease frequency of non-metal workflows that run more frequently than every 4 hours (#1064)

This PR changes the frequency that certain workflows are scheduled to be
run.
Certain workflows are run every 30 minutes, or every hour, or every 2
hours.
While these frequencies are high, which helps in keeping a pulse on the
health of the offload test suite, they are so high that PRs have
problems acquiring resources to run their own workflows. There is
significant contention between scheduled workflows and PR workflows.
This PR reduces the frequency of workflows that are run more frequently
than every 4 hours, except for macOS, since those workflows complete so
quickly.

Fixes #1065
