Bryan C. Mills 26b1694d9a testing: add regression tests for reentrant calls to T.Run 
These tests represent two patterns of usage, found in Google-internal
tests, that deadlocked after CL 506755.

TestConcurrentRun is a minor variation on TestParallelSub, with the
additional expectation that the concurrent calls to Run (without
explicit calls to Parallel) proceed without blocking. It replaces
TestParallelSub.

TestParentRun is similar, but instead of calling Run concurrently it
calls Run from within the subtest body. It almost certainly represents
an accidental misuse of T.Run, but since that pattern used to run to
completion we don't want to break it accidentally. (Perhaps it should
be diagnosed with a vet check instead?)

While we are testing concurrency, this also cleans up
TestConcurrentCleanup to use a clearer synchronization pattern.

Fixes #64402.
