Expand Linux test matrix: (#4454)

This change makes progress on the plan in #4371. It does not replicate
the full [matrix] implemented in #3851, but it does replicate the 1.ii
section of the Linux matrix. It leverages "heavy" self-hosted runners,
and demonstrates a repeatable pattern for future matrices.
