Change tstest's exported functions (AssertNotParallel, Replace, Parallel, RequireRoot, SkipOnKernelVersions, MinAllocsPerRun, FixLogs, UnfixLogs, CheckIsZero, ResourceCheck) to take testenv.TB instead of testing.TB or *testing.T, so importing tstest from non-test code no longer links the testing package and its flag registration side effects into the binary. Add testenv.Verbose to replace the one use of testing.Verbose, and a deptest check to keep testing out of tstest's dependency graph. Callers are unaffected: *testing.T and testing.TB both satisfy testenv.TB.
