Brad King 5de1e21659 ctest: Allow passing -j without value to choose a contextual default
Under job server integration, added by commit 80fe56c481 (ctest: Add
support for running under a make job server on POSIX systems,
2023-11-15, v3.29.0-rc1~324^2), use a very high default so that
parallelism is effectively limited only by available job server tokens.

Otherwise, choose a default limit based on the number of processors.

Also allow passing `0` to specify unbounded parallelism.

Fixes: #25739

Share job slots with the job server by acquiring a token before running
each test, and releasing the token when the test finishes.
