ci: Consolidate test and coverage workflows to run tests once (#11563) ## Summary Previously, the Rust test suite ran twice on ubuntu: once in `turborepo-test.yml` for test results, and again in `coverage.yml` for coverage collection. This PR consolidates them so tests run only once while still collecting complete coverage.
