Update Workflows for 6 Hour Runner Limit

[stanbrub]

Recent testing has shown that Github limits jobs to 6 hours before automatically cancelling them. There is a property to set that limit higher, but that only works on self-hosted runners. A longer overall test run is needed for iterative adhoc test runs and tagged iterations for the nightly runs.

• Break up the benchmark workflow into multiple jobs that run back-to-back
• Investigate package and tag exclusion capability for splitting up the tests
• Investigate allowing adhoc package specification to spread out over multiple jobs
• The workflows still must work for adhoc, where tagged iterations are ignored in favor of user-specified
