Fold the release's new tests into existing ones to stay within the test budget

mesh-delivery is over its budget (810 unit, 73 integration on main), so this
branch adds none net: its new cases are subtests, the three work-queue process
tests and the consumes test become one, the history stream bounds join the
stream values table, and the go/-only mesh-sdk merge check joins the one new
integration test. buildrun's 20 unit and 1 integration tests moved in from
mesh-sdk with it.
